I have been making backups of many of my dvd's. I have ripped them to my pc using DVD Shrink, DVD Decrypter, and Magic DVD Ripper. There is no problem ripping them, and they will playback fine from the hard drive. The problem is after I burn them, using Nero 6, they will only play about 90% of the way through and then freeze. DVD Shrink can't read the DVD back, nor can I copy any of the files off without my system locking up. I have tried TDK, Memorex, and Verbatim DVD+R Media, with a Sony 710A drive. Anyone seen a problem like this?
