Post subject: A Discovision Question (And an interesting Dead Side) Posted: 18 Mar 2015, 01:55 |
|
I have both a question and a Dead Side to report on two of my discovision titles.
The Question: I bought a copy of Animal Crackers a few months ago, and there is an interesting (and irritating) anomaly at the end of Side 4. For the last 3 minutes or so of the side, the film gradually speeds up to the point that it is unintelligible. The actual pitch of the sound doesn't change however, it is just that it speeds up to the point the character's dialogue is spoken very fast. The ending discovision bumper also moves in "Fast-Forward" as well, and the player (A Pioneer CLD-M301) misses the end of side code, although I have manually stopped it after the bumper ends. Upon stepping through on freeze-frame, it seems that it doesn't advance by just one frame, but it steps by two or three frames per button press.
I have looked around on this site, as well as the rest of the web for this type of anomaly, but I haven't found a definitive answer. Is it a problem with the disc, or is the player loosing sync of the disc? I have used my capture card to record what this looks like if anyone is interested in seeing it.
The Dead Side: On my copy of Saturday Night Fever, the dead side appears to be from one of those rare GM discs. I haven't watched the whole thing, but the title states that the program is from the Chevrolet Productivity Network ("Proserve"), the title of the program is "Basic Customer Relations II - The Angry, The Dissatisfied, and The Confused". I didn't see this deadside listed on the Blamld Discovision site, so I figured I'd report it here.

Sorry if it seems like a noobish question, but am I correct in assuming that only CAV discs get laserlock and runaway video? Admittedly, video defects like crosstalk and laser rot don't bother me too much (As long as they aren't too distracting), but it's laserlock and runaway video that really drive me up the wall. Also, how common is runaway video? 4 out of the 11 discovision titles I own have it... BTW, I love your site blam, the Star Trek and Discovision sections are what got me interested in laserdiscs. Keep up the good work.

Your 4 runaway titles may play better in another player. With DiscoVision, you really need to test out the discs on multiple players before deciding to keep a disc or chucking it.
CAV DiscoVision is a crap shoot. Not every disc will play in every machine. Sometimes not even another unit of the same model. If a title is clean but has laserlock or runaway in your player, try it in a different player. For example; I recently went through about 500 pieces of DiscoVision I picked up from a reseller. I play-tested every side in my Pioneer VP-1000. If the disc plays all the way through on both sides it goes on the "Good" pile. If the side has laserlock or runaway, it goes into my Pioneer DVL-919 (US). If the disc plays all the way through on both sides, it goes on the "Good" pile. If it has either issue it gets loaded into my Pioneer LD-W1. If the disc plays all the way through on both sides, it goes on the "Good" pile. If a disc is still locking up, I will try it in my Pioneer LD-1010. Out of the massive stack of discs, 2 made it to the LD-1010.
Laserlock and disc runaway are by far the least offensive issues. A clean pressing (no snow or audio noise) is a true wonder to behold. If you are serious about DiscoVision collecting, your best player is probably going to be the Sylvania VP-7200 or the Magnavox VC-8010 (actually the same unit with different plastics). A newer player like the DVL-919 will probably do okay, but the analog audio is not as good on that player.
I wouldn't attempt DiscoVision playback on Sony or Panasonic players. They simply are not tolerant enough for the pressing anomalies in DiscoVision discs.
I have some VERY early test pressings of CLV stuff from DiscoVision that will laserlock on any player - Every one of the 23 players I have. Other than these odd-ball ones, unless the disc is really defective or severely warped, you won't get laserlock.

Everything plays Discovision. Discovision, Laservision, Laserdisc, all compatible, all the same thing, same format; whatever. I cannot understand why people seem to think otherwise.
