explicit containers defined in questions 1 through 4.
6.    How can I determine if a video file that I am trying to play
conforms to the specifications as laid out in questions 1 through 4?
You can use a 3rd party tool to analyze your video files to determine
what audio and video codec is used.  A popular 3rd party tool to analyze
video files can be found at 
http://www.headbands.com/gspot/
.
7.    How do I create WMV, AVI, H.264 and MPEG-4 content? What encoders
does Xbox 360 support?
You can create this content on one of many 3rd-party applications. Xbox
360 supports many popular encoders. Specifically for encoding to WMV you
can use Microsoft Expression or Windows Media Encoder.
**8.    What specific features of Mpeg-4 Advanced Simple Profile does

The Xbox 360 supports Bidirectional Frames (BVOPs), Interlaced Frames,
Quarter Pixel Motion Compensation, Global Motion Compensation, and MPEG
Quantization.
9.    What are the different ways to play video content on Xbox 360?
You can play video from a USB 2.0 FAT32 removable drive, optical media,
and by streaming from the Zune software, Windows Media Player 11, or
Windows Home Server.
10. What are the different video codecs that are supported in all the
different ways to play video content on the Xbox 360?
See table below for more information:

* = Please refer to question 32 on how to configure Windows Media Player
to share these file types to the Xbox 360.
11.    What is the "real" max bit rate, resolution, and frames per
second that you support for all the different formats?
Xbox 360 does not specifically block video from playing based on a
maximum bit rate, resolution, or frames per second. The maximums listed
above for each codec are what we have tested for various video playback
sources. Higher rated content will not be blocked, but playback may be
less then optimal. Use higher bitrates at your own risk.
12.    What size USB storage device does the Xbox 360 support?
The Xbox 360 will support as big of a storage device as you can format
using FAT32.  Unfortunately when formatting a device in Windows Vista or
Windows XP you will be restricted to a maximum FAT32 size of 32GB.  You
can work around this limitation by using a 3rd party utility or using an
alternative Operating System that does not have this restriction.
Please note that the maximum size of any single file on FAT32 is 4GB.
13.    What is the maximum video file size that is supported?
The maximum file size for an AVI, MPEG-4 Part 2, and H.264 file that can
be played is 4 GB. 4GB is also the maximum size of any single file that
you can store on a FAT32 USB hard drive.  However, Windows Media Player
11 and the Zune software do support streaming WMV files greater than
4GB.
14. Do you support 5.1 channel AAC?
No. Only 2-channel AAC is supported. If you want to play a 5.1-channel
video on your console, you will need to encode it to WMV with WMAPro 5.1
audio or use the AVI container with Dolby® Digital 5.1 audio.
**15.    What types of AVI files are supported?
The Xbox 360 supports files encoded using MPEG-4 Part 2, Simple and
Advanced Simple Profile.  These files are often referred to as Xvid or
DivX® video files.  Many common PC DVD authoring tools, cameras, and
camcorders are capable of encoding files using MPEG-4.  Note that some
files authored for DivX devices may also contain additional
functionality(menus, subtitles, multiple audio tracks, etc).  The Xbox
360 will attempt to play these files, but does not support any of the
additional functionality and in some cases will be unable to play the
file.
16.    Why don't some of my older versions of DivX® files play?
Since we only support Mpeg-4 compatible codec implementations, we will
not be able to play video files older than DivX® 5.0.
17. Does the Xbox 360 support video artwork when browsing my collection
from Windows Media Player 11 or the Zune PC software?
The Xbox 360 will display whatever video artwork that is displayed in
Windows Media Player 11 or the Zune PC software for each video file.
**18. Does the Xbox 360 support video artwork when browsing my
collection from a USB 2.0 FAT32 removable drive or optical media?
For all video types we will search for a corresponding .jpg file and use
that as the artwork.  For example video1.avi would display the artwork
in video1.jpg if it existed.  In the absence of this file, for the mp4
container, we will search if the video file has embedded album artwork
and display that instead.  Please note you cannot use this method when
streaming from Windows Media Player 11 or the Zune PC software.  See
question number 21 for more information.
19. What is the maximum album artwork size that the Xbox 360 supports?
You should not exceed 512KB for all scenarios.  This includes embedding
artwork in the mp4 container, storing artwork alongside the file in a
separate .jpg container, or streaming from Windows Media Player 11 or
Zune PC software.
**20. How does the "Sort by Type" and "Sort by Title" option work when
browsing my own generated video content?
The "Sort by Type" option is the typical Windows Explorer view that a
computer would show your files in.  It will first alphabetically sort
your folders and then alphabetically sort your files.  The "Sort by
Title" option allows you to sort all folders and files alongside each
other.  Both of these sort options are persistent and linked to your
profile so that you do not need to set them every time.  See question
number 21 for more information.
**21. What is a sample way of organizing my video hierarchy so that I
can best utilize artwork and folder structure on the Xbox 360 for my
personal video collection?
The following example uses the sort option "Sort by Title" on a USB hard
drive connected to the Xbox 360:
·         Genre 1 (Folder)
·         Genre 2 (Folder)
·         Video 1.avi (File)
·         Video 1.jpg (File) (Artwork)
·         Video 2.mp4 (File) (Artwork embedded in file)
·         Video 3 (Folder)
·         Video 3-1.wmv (File)
·         Video 3-2.mp4 (File)
·         Video 3-2.jpg (File) (Artwork)
·         Video 3-3.wmv (File)
·         Video 3-3.jpg (File) (Artwork)
·         Genre 3 (Folder)
22. How do display modes work?
There are 5 display modes: auto, letterbox, fullscreen, stretch, and
native. You can access these modes while watching a video by pressing
Display on your remote or A on your controller.
a.    The auto setting attempts to automatically determine what the best
viewing experience is for your video. If it is a very low resolution
video, it will enlarge it enough to be viewable on your screen while
limiting the size for optimal viewing. If the video is of higher
resolution, it will it will enlarge it to fit the TV. For both
scenarios, it will retain the aspect ratio of the original video (for
example, 4x3 or 16x9).
b.    Letterbox mode will display your image full screen while retaining
the aspect ratio of the original video. Use this if you want to override
the auto function and fit the content to your TV.
c.    Fullscreen mode will display your image full screen with the
assumption the video is 16x9 formatted for 4x3 screens. This can be
helpful for older content that may be 4x3 with black bars encoded into
the video. This mode will allow you to zoom through the black bars and
see it as wide screen.
d.    Stretch mode will display your image full screen and stretch 4x3
content horizontally to fill a 16x9 TV. This can be helpful for those
who always want to fill their TV regardless of the aspect ratio of the
content. This causes 4x3 content to appear stretched.
e.    Native mode allows you to see the content at its original
resolution. Use this to view content that is extremely low resolution or
very low bitrates.
23. How are display mode settings saved?
Every time you watch a new video, the display mode defaults to auto. If
you decide to change the setting, each time you watch the same video the
console will remember what you chose last time.
24. What is the information bar?
The information bar on the on-screen display now shows you exactly where
you are in the video and where the chapters are in the file. In
addition, for downloaded content, it will also show how much of the
video has been downloaded.
25. How are the chapters determined?
Each video is divided into 10 chapters, allowing you to quickly move
around the video content. Use skip to move to the next or previous
chapter. Each chapter appears as a tick on the information bar.
**26. Can I fast forward, rewind, and skip while watching content while
it's being downloaded from Xbox Live Marketplace?
You can move around in video as much as you have already downloaded.  If
you skip or watch past the point that you have already downloaded, you
will be required to wait for it to buffer enough to begin normal
playback again.
27. Is there other 3rd party software out that I can use to stream from
my PC to my Xbox 360?
The Xbox 360 team extensively tests that we work well with Windows Media
Player 11 and the Zune PC software.  If you do decide to use 3rd party
software, please contact them directly for support.
28. How can I stream content from my Mac?
To share from a Mac computer you will be required to use a 3rd party
streaming solution.  Please note that we do not support 3rd party
streaming solutions and you will be required to contact them directly
for support.
29. After the May 2007 update, my 3rd party software doesn't stream
videos correctly. Why?
Video navigation was changed in the May 2007 update. 3rd party software
that does not support folders through network sharing will not work
correctly. You'll have to contact the software developer for support.
30. How can I set up Windows Media Player 11 or Zune to share my media
to my console?
For info about setting up sharing, see 
www.xbox.com/pcsetup
.
31. Should I continue to use Windows Media Connect (WMC) to stream video
to my Xbox 360?
Windows Media Connect can be used but is no longer supported outside of
Windows Home Server. We strongly suggest people upgrade to Windows Media
Player 11 or use the Zune software to receive the best experience for
managing and streaming content to Xbox 360.
32. How can I get Windows Media Player 11 to stream MPEG-4 Part 2 and
H.264 to my console?
By default, Windows Media Player 11 does not support MPEG-4 Part 2 and
H.264.  Your first option is to install a 3rd party MP4 DirectShow
decoder pack to import MPEG-4 part 2 and H.264 files into your library.
Once they are in your library they can be streamed to your console and
they can be played from within Windows Media Player 11 on your PC.
An alternative approach is to rename all of your mp4 files to have an
".avi" file name extension.  This will enable Windows Media Player 11 to
import them into the library and will allow them to be played on your
Xbox 360.  To enable the playback of these files on the PC, you will
still need to install an appropriate decoder on the PC.
33. I can't see my video files from the Zune software on my console.
What's wrong?
Make sure that the folders containing the videos you want to share with
your console are included in the Zune software's list of monitored
folders.
34. I received a message that says a media update is required to play
the content. When I download the update I get the message "The download
could not be completed. Please try again later. Any points you used for
this transaction have already been deducted from your balance and will
not be deducted again" with error code 80070005. Explain.
You'll get this error if you previously downloaded the media update on
another Xbox 360 console with the same profile. You are only allowed to
download the update on one console per profile. You can work around this
by creating a temporary Silver membership to download the update. Once
it's downloaded, you will be able to use the update with any profile.
**35. What shortcuts can I use with my gamepad while using the Video
area?
LB skips backward one chapter.  RB skips forward one chapter.  RT fast
forwards.  LT rewinds. Start toggles between play and pause.  X and Y
bring up the On Screen Display for more advanced options.  While
browsing through your lists of videos you can also push Start to
automatically begin video playback using the bookmark if it exists
bypassing the Resume/Restart page.  You can also use RT or LT to page up
or page down through lists of items.
**36. Why do I see the message "Updating content. This may take a few
minutes. Please wait." the first time when entering the Console video
area?
To support grouping television and game videos your content metadata
needs to be updated.  Once this process is completed subsequent entries
into the Video area will be very quick.  Please be patient during the
update process and allow it to complete updating all of your content
metadata.
**37.What changes have you made to selecting the source for Videos,
Music, and Pictures?
The source selection is now mapped to the X button for each of these
areas.  The Xbox 360 will remember the last source that you picked and
default to that.  We have also removed the computer affiliation from the
System Blade and we now show a list of all the computers that you can
connect to directly in the Select Source scene.  This allows you to
quickly jump between Windows Media Player 11 and Zune PC software media
shares.
**38.How can I play music from my iPhone® and iPod Touch®?
Unfortunately the iPhone® and iPod Touch® uses a different mechanism for
storing your music then a traditional iPod®.  We are currently unable to
play music from the iPhone® or IPod Touch®.  You can still browse the
pictures stored on these device through the Pictures area in the Xbox
360 dashboard.
**39.Can I play videos from my iPod®?
The Xbox 360 does not support playing videos from an iPod®."

Non è assolutamente OT :D
Mah, almeno avesse il lettore di HD-DVD incorporato. Comunque
scegliere l'XBOX 360 come lettore di DVD o multimediale non e' una
scelta molto oculata, visto il casino che fa il suo lettore. Sembra un
elicottero in decollo quando legge un disco. 
Per questo uso e' decisamente meglio la PS3, che oltre ad avere
incorporato un lettore di Blu Ray di alta qualità e silenzioso,
leggera' anch'essa i DivX (la cosa e' di interesse Home Cinema solo
per il fatto che verranno letti anche quelli in HD).

lol....legge a 2x....sai che bello.... aspettare 40 secondi per i menu fighi 
di alcuni bd.....


di alcuni bd.....
Chiacchere.
Coi DVD e i normali lettori spesso a caricare i menù ci metti anche di
piu' e tu gira quanto ti pare, e' il lettore di BD  che i menù li
legge piu' in fretta di tutti. Provare per credere.
Dal momento in cui infili il disco al momento in cui puoi vedere il
film passano, appunto, 40 secondi, ossia una bazzecola assolutamente
in linea con quanto hai sempre aspettato per qualsiasi DVD e spesso
anche meno.


 anche meno.
40 secondi per accedere a un dvd???????? O_o


40 secondi per accedere a un dvd???????? O_o
Ti pare tanto strano? Quaranta secondi per avere il menù ti sembra
un'eternita'? Non fai manco in tempo ad arrivare alla poltrona e a
metterci il culo sopra che hai il tuo bel menù sullo schermo, che
problema c'e'?
Prova a mettere un DVD di Disney su un lettore normalissimo di DVD.
Prima di riuscire ad accedere al film ci passano ALMENO un paio di
minuti in cui stai bestemmiando per cercare di eliminare i trailers e
la pubblicità, senza parlare del filmato merdoso antipirateria, che
grazie a dio nei Blu Ray non c'e'. Comunque io i Blu Ray sulla PS3 li
trovo velocissimi. Non capisco tutte le seghe mentali che ti fai. Ti
cambia molto se tra l'introduzione del disco passano 20 o 40 secondi?
Giusto per capire.
Per la cronaca la Xbox quanto ci mette prima che il frullatore spari a
video il film? Hai provato a cronometrare? Se si, mi comunicheresti
questo tempo mirabolante?
Ma col lettore devi vederci un film o farci le gare di velocità?
A me in campo Home Cinema pare molto piu' grave il rumore allucinante
che fa quella specie di frullatore che si collega alla Xbox e la
scarsa affidabilità della stessa, che swampa ad ogni pie' sospinto.

Ma la ps3 non ha una ventola rumorosa? 
no, č molto silenziosa.
La si sente solo (se ce l'hai vicino al punto d'ascolto) durante la
lettura di alcuni bd giochi (non film, se non proprio all'inizio,
prima ancora del menů)

Confermo, da una "ventolata" appena la si accende, e li si sente che
la ventola esiste, e poi nulla, non si sente piu' nulla, almeno
finche' la si usa come lettore br o si vedono foto.
Tanci!

 un'eternita'?
E' il tempo di caricamento di un videogioco per Commodore 64 su floppy da 5
1/4 nel 1985.
Sinceramente è inaccettabile. I giochi più pesanti sulle console attuali
oscillano fra i 20 e i 30 secondi per un caricamento completo.
L'accesso al menu di un dvd, nei casi più gravi, comporta al massimo 10
secondi di attesa.
Coi tempi che corrono, a me sembra, sì, un'eternità.
