This all sounds great, but are disk drive mechanisms accurate enough to
track sub-micron regions?  Especially consumer grade equipment?

You may consider renting one.  Supposedly, they go for about $150 or so
a day.  I'll know for sure when I try it, because I'm going to be doing some
animation as well.  Basically, you get your animation all drawn/rendered,
(at least as much as will fit on your system) and then go and rent one.
Someone said that sometimes you can rent one on a Friday evening and return
it Monday morning for the price of one day.  And these are supposed to be
the pro-editing decks with time-codes and the whole ball o'yarn.

If you don't get anywhere in the next month or two, drop me a line.
Hopefully, by then, I'll have done my first piece...(assuming I get
this weak CPU up to speed :-)

Hope that helps...

I have had nothing but friendly and helpful service from Columbia House
Video club.  The discs are rather good reproductions and I have not had to
return any for defects.  I met my membership commitment and asked to be
put on positive response (No cards to return to prevent the month selection
to be sent) and it was done, no questions asked.  I did have a reason because
I am moving and will be unsure of a new address, but they didn't seem to 
need a reason.  I will stay with the club for awhile.  I joined by phone
and stopped the first months auto shipment by phone while changing the
selection to 2 other selections.  They came in a week.  They will not
back order for you, but if they got it in stock they will ship it pretty
quick.  About the same time as Critics Choice and J & R Music World, who
are also very pleasent to deal with.
    I suggest that all phone contacts be done in a pleasent and efficient
manner.  Talk clearly and slow.  There seems to be a serious lacking in
phone etiquette with a lot of people in this country, excludig the mail
order people I have delt with.  Impatience and strong language gets you
nowhere.  Be to the point, say what you want, have catalog version, mail
codes and selection numbers ready, have a credit card ready and your
address with zip code handy.  Always make note of who you placed the order
with and when.  Make sure the price is agreed upon and know the shipping
costs.  The return policy should be known as well.  Utilizing these rules,
I have never had a problem with mail order for video, clothing, auto parts,

Dolby Stereo, aka Dolby MP, aka "Dolby Surround" is the encoding method for
including "center" and "surround" channels in a stereo format.  SR is an
updated Dolby-A full-spectrum noise reduction system.  SR may only be used
in the production of a film, and not in the print soundtracks.

Umm, what new 6-ch analog format?  The new Dolby SRD is a reduced-bit-rate
digital system that stores the data bits for 6 discrete channels in between
the sprocket holes on the film.

70mm analog sound is 6-channel discrete magnetic analog with a linear speed
25% higher than 35mm's 2-channel optical.  SRD can also be used on 70mm, and
presumably is not as lossy as 35mm.  Despite the fact that virtually all
films are shot in 35mm, 70mm prints have other advantages than improved
sound, such as:

* brighter lamps can be used due to the increased area, resulting in a
  brighter picture and less flicker.

* reduced resolution loss when printing up from 35->70, vs 35->35.

* simpler spherical lenses may be used in the projector (compared to 35mm
  anamorphic), reducing internal reflections, aberrations and contrast loss.

     An R5 was brought into the shop next door (The R5 is moved around a lot
and does remain unplugged for extended periods of times).  The complaint
was that there was no power.  The switching IC used refused to turn on.
From what the Tech's said, the IC was fine but required voltage at one
of the pins to turn on (No I don't know which pin and I haven't directly
talked to the Tech who fixed it, and the R5 is out in the field right now).
Even touching the pin was enough to start the IC.  The Tech added a resistor
to see if that will correct the problem.  I'll take a look at the R5 next time
it comes in.  The tape is stuck because there isn't any power (even to turn
the motor).  I don't know if it is in the FAQ archives but there was a thread
on why the tape wouldn't eject so you might check there.  (In your case it
is because of no power,  generally it may be becase of a broken, popped, etc
belt).  Depending on the cause and type of VCR this may be done manually
(with Hitachi's this seems to work fine) or by powering the eject motor
(after you disconnect it from the circuit) with a battery.  MAKE SURE YOU
KNOW WHAT YOU ARE DOING and that it make sense to eject it that way.
     IF you have the service manual and know a little about switchig
supplies (or know someone who does) you should be able to tell where to
put the resistor.  I'll check to see if Sony has a fix for this next
time I go down there  (in a month or so),  If they do not and the resistor
fix seems to correct the problems I'll post the modification.

I have a copy of the cheap (~$30.00) Fantasia LD that I played for the first

portion during various parts of the feature. The first one occurs during the
eighth minute of play of the first number. Other occurances seem to happen
on the first side only, I didn't percieve any on the second or third sides.

My questions are:

1.) Is this a typical LD problem?

2.) Has this been reported by anyone else on Fantasia?

I'm going to mark down all of the places I hear these "volume drops" over the
weekend, and have someone else try it out on their LD to make sure it's not
a player problem. Any help or suggestions here are appreciated.

Please excuse my ignorance, this is the first LD I've ever seen.
