My turn, I guess, to answer this oft asked question.  Go 8mm or 
preferably Hi8.  VHS has 230 lines of video resolution.  8mm about 
330 lines.  Hi8 has 400 lines.  The higher number of lines results 
in a VERY noticeable quality improvement, even on poor quality 
TVs.  400 lines resolution exceeds what most broadcast stations 
transmit, while 230 is significantly less.  Plus 8mm format will 
record for 2 hours, while VHS-C is 20 minutes.

Sony cameras use a focusing system that digitally attempts to 
maximize contrast in the image.  The newer Sony's like the TR101 
and I believe the TR200 are faster at focusing than the TR81 and 
lower models.  I'm not sure about Canon, but some other makes use 
infra-red focusing.  That is supposedly very fast, but will have 
some problems in poor light, shooting through windows or other 
conditions.

I'm looking for a Hi8mm vcr that puts down an RC time code.  We need this
so we can get to an exact frame without too much difficulty.  I talked to
a Sony rep and he says that Sony does not make such an animal.  The 
closest they come to such a vcr is their EV3000 that puts down a time
stamp on each frame but this only gets you to within one second of the
recording.
Does such a VCR exist or does it only exist in the VHS formatt at this
time?

thanks for any help

"Simple parts" indeed. My 6-year Ricoh warranty covers motors, the CCD,

it, that's good enough for me.

Looking for a cheap pro-logic surround sound decoder? I noticed that
the warehouse chain PACE has a Paramount Pictures pro-logic surround sound
decoder plus two (cheap) surround speakers for $199 (+5%). This seems
cheap to me.
	- Remote control
	- 25W for rear channels
	- Appears similar to the old Audiosource SS3

Maybe someone who's played with one can post his comments.

Its been a while since tape rewinders have been mentioned, but I
noticed that Radio Shack sells a VHS tape rewinder that allegedly has
an end of tape sensor.

Anybody seen a review or have first-hand knowledge on this puppy ?
A local outfit has refurb units for sale at $399. Seems to have all
the features I need, and the specs are good, though not outstanding.
It uses the PMI chip which I believe to be a good one. I understand 
that this receiver is discontinued, but haven't been able to figure
out what it's replacement might be - there's a model called the 2000
but it's priced quite a bit more at retail than the 610. Any clues?

That is why any digitizing system must have a steep filter at the front
end before the D/A converter to prevent this from happening. A more
mathematical way of looking at it is that for the "proper" result you
must sample the image at, say, 4X the final spatial resolution and then
use a classic DSP algorithm to convert that into a quarter of the
number of samples in one spatial dimension (the mathematical term is
call "decimation").

	I've been purchasing my plastic outer sleeves from a booth
in the Pasadena flea market (1st sunday at the Pasadena City College)
specializing in record albums. The 3mil thick variety, I believe were
selling for $3.00 for 25 sleeves. I've used this on single-disc
and two-disc releases, and can (just barely fit) 3 disc, gate-folded
package (like Criterion's CLV Close Encounters).

	I've also bought larger sleeves from them that were big enough
to cover large box sets (Looney Tunes vol1&2, Alien, Aliens, T2), with
plenty of room to spare.

	Last time I was at this flea market, I asked the owner where
I could find her the rest of the month. Here's the address. She said she
does mail orders too.

	Far west Record Supply
	Paper & Poly Sleeves
	Marsh Weeks, owner
	P.0. Box 3027
	San Dimas, CA. 91773
	(818) 335-5544

	Finally, I asked the owner who her sleeve supplier was. She said
she orders them from a very large sleeve manafacturer (sorry, I forgot
the name) that has a full page ad in the back of GoldMine magazine.

Photo CD has great potential, but I would not recommend any current stand
alone photoCD player.  Take a look at any of Kodaks ads for photoCD that show
a photograph and the equivalent on a TV screen -- notice anything odd? 
Kodak's photoCD players crop the image quite severely!  The reason? 
Presumably it's the same stupid reasoning behind the existence of pan & scan
for video transfers -- print film has a different aspect ratio then your TV
screen and Kodak is worried that people will dislike black bars that would be
neccessary to show the full image.  Why didn't they just allow you to resize
the image to fit your own needs so that you can crop it or see the whole image
as you desire?  Who knows?

Note that the full image is stored on the CD, it's just that Kodak's photoCD
players (and other brands I've seen including Phillips CD-I) crop the image to
avoid black bars.  Note that if you use photoCDs on a computer you will get
the full image and you can utilize the computer to frame the pictures as you
see fit, or use them in documents and applications, etc.  That is where it is
quite useful and powerful, but until there is a standalone player that allows
you to show the image fully (and allows you to adjust the size to compensate
for TV overscan and such) I would stay aware from stand alone players.

A properly operating video game console won't degrade a monitor any more than
any other video source, hardware-wise.  Games often include warnings about
burning static images onto the screen.  It would take a pretty long continuous
exposure (days-months?)  to effect a modern CRT.  Non-CRT technology screens
may be more susceptible.

Video game software *can* exercise a monitor much more than regular video
though, due to the screen content.  You tend to have more fully-saturated
colors and rapid transitions.  For example, "Super Mario World" has a lightning
effect that basically goes from full-screen black in one frame to full-screen
white in the next.  My XBR has a hard time with this, and the screen "shrinks"
momentarily.  TVs are built to handle typical content, not extreme cases...

Our experience with personal computers has been that the hard 
drives seem to give us the most problems, grinding to a halt, or 
not restarting.  Since this is a mechanical device, I have been 
inclined to turn off my work computer overnight, to eliminate 
about 60% of its operating time.

I was faced with the decision of buying Mitsu or Sony just a while ago...

The Mitsu was very close to the Sony 696HF (which I ended up buying).  
(I'm sorry I can't remember model number of the Mitsu which was comparable
to the Sony 696).

As mentioned here by others, the Mitsu has a faster rewind and I think
the tape movement mechanism is faster (less time from when you press 
play till the picture comes on).  

Several things which I liked about the Sony which the Mitsu did not do:

-index marks on prerecorded tapes (as mentioned by others)
-the Sony had 8 event timers while the Mitsu had 4 (I believe).
-the Sony was about $40 cheaper.
-the Sony 696 remote can control other TV's.  It's not a learning remote
 but insead it's a pre-programmed one which will control other TV's.

Well, I can't remember all the details right now...  But I've been pretty 
happy with the Sony.

Actually, the surround is L-R.

If your cable monopoly supports MTS stereo, any surround encoding in the
original signal will still be present.  If they don't support stereo, 
you are hosed.

I agree with Dan.  The ghosts you are getting is due to the fact that
the signal received at your antenna is the sum of two signals:  
(1) the direct signal from the station and (2) a signal which has 
bounced around some downtown high rises.

The first signal is probably the strongest and the others are the 
delayed ghosts which appear on your screen.

Perhaps a signal attenuator will do you more good than an amplifier.

If you compare a photo CD to a good Kodachrome slide you will find that you
aren't even in the same ballpark. I'm not sure how you would derive a pixel
equivalent to the silver halide grains in the film, but it is overwhelming.
I think that film has an even wider dynamic range than the photo CD, but
I'm not absolutely certain.
