I assume DVDShrink requires the presence of the ts_iso file as I get "file not found" messages when I omit it. But if I use DVD Decrypter and chose to back up only the main movie files it doesn't include this file. From my very rough understanding of DVD file structures I am assuming that ts_ifo acts as a "contents page" for the vob and other ifo files. To stop rambling on and come to the point can I include the ts_ifo file along with the main movie files or will this cause a problem as it'll refer to files that I haven't included. If I don't include it is there a way I can load the main movie files into DVDShrink.
