I backed up my DVD using DVD Shrink using the burn with Nero option, Plextor burner, Memorex DVD-R media. It plays in all 3 standalone players I have (one is a combo tv/dvd deal). But it will not play in my Playstation2 (gets unable to read disc error) and it will not play on either PC with PowerDVD 4. On my PC, it locks up when the program loads and I have to end task and then reboot to unlock the drive. On my wife's PC her got an error after a while saying that the CD couldn't play because it was probably scratched or dirty. This was the first time I ever burned a DVD, so any suggestions as to what method I should use to get it to play on everything and also should I be using DVD-R or DVD+R.
