Either that or the player's just rejecting the massive plot contrivance... (c'mon, "fire everything" would've blown that BOP up before it could get in a third shot!)

How does one try to flatten it back out?

By default think everything is rot.

About :57 is when I try to fast forward, then it jumps back.

I use plate glass, sunlight, & water to flatten warped LDs.
I know that sounds very... hmm... granola, but I've described the process before. Sandwich the disc between two plates of glass & leave it in the sun to warm up, then in late afternoon before things start to cool down, put a jug of water on top of the assembly to weight it down. That way, as it cools overnight, it loses the residual strains which would otherwise bring the warp back. Take the jug off in the morning & repeat. After three or four days, the disc should be flattened, with no more tendency to warp.

I'm trying to think back maybe 18 months or so when I got ALIEN Dolby AC-3, side 1 near the end of the disc skipped and jumped forwards and then stopped. But I never used any glass sheets to sandwich the disc with books for weight on top. I just placed the disc on the rack shelf in vertical position and left it as I wanted to look for another ALIEN AC-3 pressing but oddly the trouble sorted itself out over a few weeks and now it plays fine.

I bought Star Trek V-VIII for $5 each at a used books/video store last year. I'd watched all but Generations (if I'm not mistaken). Watching it today, get to the Enterprise crash scene, and...bam, no workie. Audio starts popping out, video starts to glitch, heck, when I try to fast forward past it the player either jumps back to the beginning of the rot or runs backwards! I saw there was only one report of rot for this one, but I guess it had to happen sometime. Pretty sure it's not the player since I also watched High Noon today and all three sides of that are CAV. This copy was in good shape too, even still has the shrinkwrap around it.

Good day to you thewhitefalcon, I hate getting rotters................ Kind Regards

not always true. if its only at one spot it could still be something with the player, I take it since you only have about 19 discs you don't have a second player. please post a video so we can see that it truly is rot. thanks, P.S. I just picked up about 30 discs, I have about 5 more discs to watch and NONE have rot. so now my collection is over 400 with no rotters and only a handful of those I had to replace I did ever find a rotted one over the past 20+ years. ________________________________ the rein-o official signature:

This ISN'T rot. This is a warped disc. The crash sequence as at the very end of side 2 which is CAV. If you can get the disc to flatten out, it should play fine.

yep like blam said, the laser is having trouble reading as it will be too far or too close for the focus to read the disc due to it being warped. ________________________________ the rein-o official signature:

Nothing in that clip to suggest it's a rotter. Rot usually produces multi-coloured speckles and other A/V distortions. I'm going with the warped disc theory or a possible player issue. Try placing the disc on a flat surface and see if you can slide a coin under the outside edges or close to the centre hole. Rotate the disc and check for unevenness.

Eh, I've seen worse. Abramstrek for example. The disc does seem to have a slight warp to it, so I'm trying to flatten it back out.

We need a sticky here that explains laser rot facts, as best they can be known, and a few of the crazier theories since they sometimes contain truth. Noobs by default think everything is rot. There are YouTube videos of guys playing LDs and saying "this here is rot" when it isn't rot at all, that doesn't help.

A sticky thread focusing on laser rot isn't a bad idea. In this case the problem was apparently caused by the disc itself being warped or something in particular. I think it all comes down to our own eyes and how sensitive we are to speckles and other imperfections. I, myself, am sensitive to "things that shouldn't be there" and I believe that when playing the movies on bigger screens today, the image reveals a lot more than back in the days of the smaller good old crt-screens. We all have been noobs when getting into laserdiscs, remember that, and that we have been educated along the way. The term laser rot is in my honest opinion a negative subject that could rise an anger and it hurts the community if we get really mad at each other. The LDDB.com page clearly says that "laser rot can happen anytime during the lifetime of a disc, so this is a problem important enough to deserve its own page." Funny to read about people having a big collection with several hundreds of laserdiscs and can tell that their collection has no rot whatsoever, though I take those statements with a grain of salt. Of course, they could have been extremely lucky with all of their copies, but who can tell? None of my approximately 160 discs (per today) are 100% clean. The "uncleanliness" has been caused by light to mild laser rot and other imperfections such as being warped, scratches, glue residue, etc. I can't say for sure in every example, but some of the titles have a higher tendency to rot. I can't even say for sure that the movie I saw two years ago is going to look exactly the same today. That's the life with laserdiscs, an investment can turn into a loss.

It can be removed but you need very patient has it can take some time with sticky sellotape and smooth corned edge maybe as long as you don't poke it and scracth the disc up worse, and I can see everyone's face here thinking I had it on Willow PAL pressing where I accidentally scratched the disc on the outer side of side A which is near to end of side A. I have the Same STAR TREK GENERATIONS pressing so this near the end disc on chapter 12. I can see where the trouble is and I have my frame count up to see how much frame time left but I can't see the time on my DVL-909 so I'm guessing a few inches away from the outer side of disc 1 side B. Take a close look and tilt the disc at angles and look within a few inches of the outer-side of disc for any rough looking scratch marks. By the way the crash scene in Dolby AC-3 is breathtaking!!

You think it could be a warped disc rather than a dodgy rough scratches on the disc surface as the sound when it pulses or the PCM signal is stuck with the picture sounds like scratch to me. I'm trying to think back maybe 18 months or so when I got ALIEN Dolby AC-3, side 1 near the end of the disc skipped and jumped forwards and then stopped. But I never used any glass sheets to sandwich the disc with books for weight on top.

So the glass and books for weight might sort out his troubles in maybe a few days?

Standing it vertically on the shelf, with no side pressure, will allow at least the milder "impressed" warps to relax after a few weeks. More severe warps, or those which are caused by internal residual strains rather than by mechanical forces, require stronger measures. The dear departed disclord told me that his father had actually used an oven on low heat to deal with certain early Pioneer pressings which had internal-strain warp. You could tell these because the warp would keep coming back. But by heating & then cooling them under pressure, the strains are gradually relaxed.

I need to put this in my new player, but I suspect it was a player issue. It was having issues with the ends of CAV discs.

publius, Some may leave the Sunday roast over-cooking! I don't think I'd be putting any of LD in the microwave on (oven mode) I might forget and have it on microwave. I think the technique of glass on the table and laserdisc placed on with another small bit of flat glass placed on top with a few thick "yellow pages" to weight it down for a few days is best.
