I have been sent to this forum for some advice and hopefully a solution. In a nutshell.... got a new computer and backed up a movie that plays in computer, stand alone player and ps2 but Not in the xbox.(previous computer backed up readable discs for the xbox). I am still using shrink then a burning programme (have used record now,nero and decrypter with no xbox success) My media has not changed from what I was using on old computer dvd+r ritek R03 (same spindle ) So I presume by process of elimination it must be the new burner Nec DVD RW ND-3500AG. Any ideas for overcoming this problem would be appreciated. Thank you.
