one2one backup copy

[wrecked4]

just something funny i came across.
i put the original copy in my drive and previewed it with powerdvd. then i imaged it with DVD Decrypter and then burnt it. then i played the backup copy with powerdvd and it asked me if i wanted to resume play or start form the beginning. now that's what you call one2one copy.
one more thing is there any way to have the vob's on different drives and have dvd shrink, shrink them.

"is there any way to have the vob's on different drives and have dvd shrink, shrink them."

If you mean multiple FULL DVD "packages" residing on different drives and/or partitions (ALL .IFOs, .BUPs, .VOBs) to be accessed for "Re-authoring" and combining, then sure...

If you mean individual .VOBs, or other PARTS of a FULL DVD "package", then no...
