I am a bit confused here. I have a Plextor PX-708A that was built into my new computer in December 2003. The computer is a P4 2.8gHz, 1gb ram, dual 120gb HD Raid 0 and dual 200gb hd Raid 0 running XP home. I have always had great backup / burns with this drive no matter the media. I consistantly use the Ridata +R from Newegg and am lucky to coaster 1 out of 100. Lately though my backups are skipping and jumpy. I've blown out the drive and even as a last resort ran a lens cleaner. I usually use DVDFab Decrypter or RipIt4Me, then VOB Blanker, then Recode or Shrink and finally Nero Burning Rom (6.x). Side note: My buffer stays at 87% - is this an issue? I think it has always been about 87%. Any thoughts or way to test the drive? It's really odd. Some of the backups that have given me problems are: Casino Royale, the Prestige, even Dukes of Hazzard - the Beginning. I have no issue ripping them but in the last 2-3 weeks my playback issues are huge. Any thoughts? Greatly appreciated!! Thanks all.
