Ok, been happy for years. PC computer. Backing up my DVDs using the variety of programs such as DVDShrink or Decrypter. Used Nero to burn + a Plextor 708A. Only complaint was even stripping down to basic movie still led to compression and notable glitching when trying to watch movie. So swapped up to a Plextor 760A-Dual Layer Drive. I figure if I rip movie, can burn it to dual layer 8.5 GB DVD+R DL disc and don't have to compress. Worked on installation, and upgraded to latest firmware-1.05. Friend gave me some blank Memorex Double Layer DVD+R DL (double capacity single sided) discs (8.5 GB). They burn at 2.4X. Tried to burn, and movies won't play. Is it the media? Is my initial plan to burn on bigger discs without compression flawed?
