Hopefully this is the right forum for my problem. I have 3 NEC 3520’s, a NEC 3540 and a Sony 510 recorders. Heres the problem. Early this year I noticed that DVD movie’s I burned 6+ months earlier wouldn’t play on my set top players anymore. I would get pixilating and eventually the player would lock up. I have 2 JVC players and a Philips. These players played these movies fine right after I burned them, I’ve watched every one. To my suprise, these discs developed alot of bad blocks as checked with CD/DVD Speeds scan disc and also DVD Info Pro. I scan every disc I burn with these utilities right after I burn them and have never had any bad blocks show up, but yet after 6 months these discs are full of errors. Now these were a medley of discs including CMC, RichoJPN, and Verbatims. So now I re-record about 300 movies on Ritek 8x DVD+Rs which are R03s and some Optodiscs. Last night a grab a disc I recorded 7 months ago to the day, put it in my player and it locks up tight. Grab another discs that was 6 months old and it played for about 5 minutes before it started skipping and pixilating. I put these discs in 2 of my Lite-On readers in 2 of my PC’s and scanned them, Once again full of errors. I checked a few more and they too have errors as well. Now heres something I really don’t understand. When I copy a movie I use either DVD Decrypter or DVD Shrink to make an ISO image of the movie. I burn the ISO either with Nero or DVD Decrypter, then I WinRAR the ISO file into 50mb parts, generate some par’s and burn that to another DVD as a data DVD-Rom. I just scanned some of the backups and they have no errors, even the cheap CMC discs are fine, It’s just the discs burned as movies going bad. Can anyone tell me why these discs are failing ??? I have music CD’s I burned 5 years ago, stored the same way, in jewel cases and their fine, with no errors and most of my CD’s are cheap free after rebate CMC’s. I do use Stomper labels but I can’t see them as being a problem. DVD’s unlike CD’s have the recording layer sandwiched between 2 discs so the adhesive isn’t coming into contact with it. It also can’t be a balance issue as these DVD’s test fine when freshly burned. I can’t be the only one having this problem yet I haven’t see it mentioned before. Anyone have any idea’s ???
