In your documentation you state that I should use the IFO file from a DVD because it contains all the movie files references I need for converting the movie. Video, audio, synchronization are preserved. But what if I only want the core part of the film? How do I remove the unwanted VOB files from the movie copy i want to create. Unwanted parts being, Previews, warnings etc.? and still maintain synchronicity ( tha's a big word!) ? Ususally in most films there are 3 or 4 VOB files that I want to use. Thanx for any assisstance.
