dvdxcopy

[ADLER]

so far I have successfully backed up several DVDs onto 1 disc, and several split between 2 discs.

I believe that I just have the Beta version as well, but seems to be working. What I do, is just select ALL titles over, and hit copy. When it has copied all that can fit onto 1 disc, I burn that disc. I then test out that first disc to see if it fit the whole movie on it. 9 times out of 10 the whole movie plus beginning intro/menu is on the first disc, so I just don't even bother letting it create a second disc. The only stuff that shows up on the 2nd disc is deleted scened, etc. which to me isn't really worth it.
If the whole movie didn't fit onto the first disc (ex. Lord of the Rings) then I allow it to create the second disc.

I hope that made sense, and helps.
