I am kind of a purist in backing up my movies and don't like compressing the movie ( I can tell the difference). But, when I am backing up my movies that have only 1 titleset splitting does not work. After the first disk is burned the program asks for the original dvd. It reads it for ten seconds then asks for a blank dvd. It spits the blank ( no longer a workable blank dvd) out immediately and does not copy the movie. This only seems to happen when there is only one titleset. Any help is much appreciated.
I am of the same opinion about compressing a movie to fit a single DVD and also split a long movie to fit 2 disks.
Thus far I have found that CloneDVD2 does an excellent job of splitting long movies. You don't need to split by titleset. You can split by chapter. Of course, if your movie doesn't have chapters, it won't split.
It also gives you the option of removing annoying cr*p like the FBI warning, 2nd languages & subtitles, etc, if you have AnyDVD (see below) running.
Most copy programs won't burn copy protected DVD's, so you might want to download AnyDVD from them too.
This little TSR runs transparently in the background & strips ALL copy protection from DVD's & CD's.
