Hi, I'm new to DVD backups. I just backed up one of my DVD's using One Click DVD which worked great - however Windows XP says the DVD-R (RITEK 4.7GB GO4)is now 6.7GB?? How can this be - it says it on 2 PC's? Weird huh? Any suggestions as to why? It plays back fine - no problems. I actually am considering purchasing One Click DVD ($49) as I downloaded the latest copy of Shrink DVD and it could not rip the DVD - saying "copy protection I/O error" about halfway through. Any suggestions? Any advice would be great!
