Question: Can I stream or get my Amazon purchased shows to play/download on this unit?
Document: This was purchased to replace the Wii for watching Netflix. The Wii couldn't get a strong WiFi signal we replace it with this device. At the same I purchased the WD Livewire Powerline AV Network Kit (actual real-life Plug 'n Play). The WD Hub has been able to stream every video file I've sent it with the exception of an MS .asf stream. Vocal/Video synchronization is top notch. I'm enjoying the bundled services, particularly Netflix, Pandora and MediaFly. It would sure be great to add Amazon Video to the mix.How can it be improved ?
I was very excited about this product,it would have eliminated my need to move my desktop PC,closer to my HDTV when ever I wanted to watch my ripped DVD or Bluray Discs on big screen.The device is extremely slow and sometimes non responsive,I have to consistently reboot the unit.I have followed all the instructions,however this device is extremely difficult to share on the network and I cannot get any of my content to play from the device via my home network.No content shows in Video,Music,etc.I can only play videos via direct USB connection to the WD TV LIve HUB and then at times the videos stick and I lose audio,playing directly from my computer is without problems.Thumbs dumb to Western Digital for such a buggy product and thumbs down to Amazon for selling this.Amazon I will be returning this for a FULL REFUND.
I highly recommend it. I purchased mine from Amazon and it came well packed. I bought it a few months ago and finally got it installed a couple of weeks ago. The remote control is great. The first thing I did was check for firmware updates on the internet and the WD Media Hub found a new update. I let it download and install it. I had the WD Media Hub do a sync from my intranet system and it located all of the movies and videos that I had on the NAS Drive and on all of the computers that I had set up a public share on.Great unit and worth the money.
First, get a wireless adapter for 10 bucks. I take it travelling and if you need to connect hotel wifi, it is a must. Second, download the WD cell phone remote control app, for without a controller it is dead in the water (wireless adapter is needed to make this work too). Third, invest in a bluetooth keyboard to link with the unit via the front usb port, add the dongle for it there. Also download a DLNA app for your phone, tablet, or computer to stream to this unit.
I purchased this a couple years ago right from WD for $150 which is cheaper than its selling for here. I love this thing. Works great and never chokes on any files that I download from the internet. It shows up on my network as a storage device and files are easily dropped right onto it from my Mac.My only complaint and why I gave 4 and not 5 stars is that you cannot download any additional apps onto it that are not already on there. It comes with a limited amount of apps.
I purchased this unit today to replace an aging AppleTV, unfortunately there are some basic flaws that will force me to return the unit.The most major flaw is that the album artwork is considered as regular photographs, so that when I play the music with a photo slideshow, I get album artwork popping up between my family photos, really annoying. This is caused because the unit doesn't work with folders, even if you load the data into folders it flattens all of the data into one big mess, then determines with are photos, music files and movies/videos on it's own.Second problem, synchronization with a USB drive.
The WD TV Hub has 1TB of internal drive, can be connected via etherport port or thru wirelesseasy enough for everyone to use. I know the 1 TB isn't big now-a-days but it's a good start for WD and can hold a few hundred movies, thousands of photos and music files.Just remember if you have subtitles on your movies to have sub and movie with the same file name( XYZ.AVI and XYZ.SRT or XYZ.sub  as example) otherwise the WD won't be able to recognize the sub for the movie you're playing.It has two usb ports (1 for your wireless USB adapter and the other for 1 external drive - for me anyway) and 1 HDMI portI do recommend to arrange your movies by Folders/Genre (and yes it will show as folders for easy movie search, but it won't if the folder is empty)mine is setup to 12 different folder/genreOne minor issue I found the WD Discovery tool will always recognized the same old ip address (it's a minor issue so just try keeping the IP Address the same or manually input IP address or setup IP on your system/router to bind to WD)You can also setup to stream videos (its a hub) from your other computers if or when the 1 TB is filled.No manual or cd's are included but can be easily download on WD's website, and firmware update can be done via usb or if you have wireless connection automatically.netflix (stream only $7.99 month, facebook, blockbuster, amazon and few others are avalaible for feesonly problem is the software that your download for the Player (WD Discovery), it doesn't seems to recognized dynamic IP after it's been given an Address (solution just make sure Player's IP stay the same by manually inputting it on the WD setup then make necessary changes on your Firewall if firewall doesnt auto it for you)oh ya - don't buy the Iogear USB Wireless for this Hub (see my review for it) Asus N13 works great with WD HUBUpdate 8-30-2012 : product still works - almost on 24/7, WD update are better than ever .. added an extra 1 star for total 5 star rating
Sometimes if I restart the device a few times a missing one will appear.Adding content - any time you add a video the device recompiles the entire drive, a HUGE waste of timeSpeed - VERY slow, when first purchased it had a few lags here and there but now it completely stops every few seconds.Updates - this is a  total joke, when there are firmware updates it takes at least 3 tries to get them to download and install. Typically the device will freeze when its almost done and needs to be completely restarted
I bought this for my dad who is 76, so he can watch old movies I have ripped for him. I hooked up my usb external during  set up and it took overnight to download all the files to the 1tb drive onboard the unit. I give three stars for the lack of built in wireless (I bought a usb n dongle from asus for 19.99 on amazon), and the fact the onboard menu system is clunky. Maybe I am just too used to the smooth flow of XBMC. Streaming is a tad slow to other rooms, but I cannot fault WD for that.
I purchased this unit to replace another brand which had access to both Netflix and Amazon Prime. This unit will not allow access to Amazon Prime which is important to me. My prime interest is in streaming movies from various providers, but the unit falls short without access to all streaming sources.
Answer: Hopefully someone from Western Digital sees this question and other comments like it.  It they would integrate a browser and additional Apps like Amazon, Vevo, FSTV, etc, (come on WD - this is a great product - take on Roku directly!), this thing will sell like crazy.  They have really improved it and it is almost there.  Raise the price a few dollars if that's what it takes - and pack this baby with streaming apps!  Someone in product development needs to understand how close they are to a serious Roku killer. . .not to say that Roku isn't a good product too.
