Hello, I know CRC errors are the talk of the town around here, but I feel like I have a whole different animal on my hands. Let me try to make it as basic as possible. I have two Dell machines. They are similar, but not identical and have different dvd burner models. One machine has a burner manufactured earlier (it's older maybe by 8 months to a year). Every once in a while I get the CRC error, maybe 1 in 50 dvds I backup. This month, however, the machine with the older burner has gotten CRC errors every time (maybe 4 discs in a row). I read here that this could be due to a scratch and whatnot on the disc, BUT, all of those discs backed up smoothly on the other machine, no problem. I also read Mr. ScubaP talk about it having to do with faulty optics something or other on the burner. Does this sound like one of those cases? It's got to be a very early DVD burner; I know it's a Philips, that's about it. This is all being done of course with DVDShrink, without the help of DVD Decrypter. I also updated DVDShrink and Nero (although Nero isn't a problem right now) after the first error and have still had the problem since....phew, ok, I hope I’m not being long winded and uninformative. Thanks for any comments.
