Which One To strip Out ?

[Master Yoda]

OK this is strand, in my computer windows says the dvd is 6.93gb, but when i rip all the files to my hdd its only 5.17gb,dvd decypter also says its 5.17gb.

Right i'm doing a full backup.Theres two vob sets on the disc, the second vob set has 3 program chains,two are 5 mins and one is about 15 mins.I need to strip out one of those chains as its a trialer that starts before then movie,im gonna use ifoedit to strip the chain, but i dont know which one is the right one.

Second question is that the first vob set is the movie, but it has two program chains the first is the movie then the second i dont know what it is as its only 25seconds.How do i find out what that is, so if its nothing i can delete it.

Have you used DVD Shrink ? I think you may get on quicker with that.
