I got one copy of Stasrhip Troopers yesterday. The seller said it plays fine. Well, its watchable mostly but there are few pretty bad areas of few seconds where even the image gets lost. During the whole movie the picture sometimes just tilts slightly up/down and frame drops appears. So i guess, yup, my first rotted disc I reported it on the database.

I am recycling bad discs: no point having them take up space. Black outs are not rot. Do you have your player straight into the TV or are you using some type of processing?????? If you have an enhancer then i'm sure thats what is giving you the black outs. Good luck. ________________________________ the rein-o official signature:

When we say "rot" we don't mean "detective in some way" we mean a very specific defect that can cause a number of problems but is usually colored snow and digital sound defects. Not every disc defect is rot.
Honestly, I'm pretty sure %99 of all reported rot is another issue misdiagnosed. Yes I also think the rot issue is often misdiagnosed in many cases. When Pioneer took over the US Carson plant they worked very hard on what they called the "color flash" issue that they fairly quickly put down to various things like quality problems with the (then) variable consistency of the disc components that were being supplied to them & the very poor cleanroom conditions which were promptly improved (basically by being totally rebuilt within the building with the Pioneer spend at the plant standing at just over US $10,000,000 in refit costs alone by July '87) which dramatically improved the quality of the final product. During the lifetime of the format Pioneer never referred to laserdisc age deterioration as "laser-rot" & put the "color flash" issue down to production or material problems throughout the formats life. The laser-rot problem with LDs does exist but perhaps is missread by some (maybe by myself in some cases) but sadly the deterioration can be ongoing - I have a few LDs that played well many years ago but over the years have succumbed to the dreaded rot but others have displayed high levels of "color flash" from new but have never gotten any worse over the years so would that not be a production issue & not rot? Whatever way you look at it "rot" is horrible but thankfully we can check here to see what LDs should be avoided or at the very least checked out before trading/buying the disc/title.

dutchinmiami wrote: I stand corrected: it may be a messed up disc and not rot. Nope i still don't think so. Black outs are not anything i've ever had, and this is not rot or a defect. I believe it has something to do with your setup and its like the signal is dropping or not in sync with your set. How is your LD player connected and have you changed anything to see if that fixed the issue. remove the scaler etc from your chain. ________________________________ the rein-o official signature:

Discs with no issues play fine. Discs with issues black out on the CLD-1010 and do not spin up or fail on the CLD-2080. Then it sounds like the refresh rate on your TV. Black screens are not rot. Only thing is that some silent films may be missing frames and will display as black. Good luck with it. ________________________________ the rein-o official signature:

Same with First Blood Part side 2: will not / hardly play at all on any player.
Thanks for the input though! Yeah, after looking at your collection sounds like you picked up a bunch of warped discs not rotted. Good luck. ________________________________ the rein-o official signature:

On side 1 such bad spot is exactly on chapter 20 mark and player even cant find it but when rewind it a bit the player passes the chapter mark with such blackout and then goes on normally. https://youtu.be/l94QphokiNAYeah, I don't know what that is exactly but it certainly doesn't look like rot. The only defect is a loss of sync with no other obviously contributing factors. A rotter will usually only lose sync once the rot is so bad you can barely see the movie through the rainbow of snow. That being said, due to the very physical nature of LD and the way it stores all sorts of signals on one track, there are variously weird and hard to explain things that can result from rot. Usually it's just snow, then worse snow, then the digital sound quits, then the disc won't play at all. This could be any number of defects, but it doesn't look one bit like rot.

That is not a rot? Well, what could that be? Discs doesnt sound warped, no any weird noises from inside. I will clean discs carefully, i didnt do that when i get them, just a rough visual sight when they seem to me very ok. However, i use no scaller, just a single composite cable straight to tv, if that is concerned. Once again, this release is the only one i have with any issues, no any discs i have have any issues and play fine.

My guess is dirt but you need to clean the disc, remember when you put it in the player it reads from the bottom. Sticker will say side 1 but that really is side 2 to the player, it reads from the inside out. it could also be like zeta said another flaw, something so small inside the layers that is making the laser read it. ________________________________ the rein-o official signature:

I had some time yesterday to inspect these discs carefully.... Honestly, i cant see anything! No any weird marks on the surface, dirts or anything, i even didnt clean them as there is actually nothing specific to clean. I took disc one only, it looks like any other in my collection, even better. Yes, i Know the labels are reversed, it is clearly visible CLV and CAV surface. Ok, if thats not rotted disc, i dont Know... can anyone upload examples of rotted Starship Troopers? I cant see any such video noise matching the laserrot description, only these tilts, drop frames and blackouts i uploaded on video
