The "files" are actually Titles and in most cases they don't actually exist as different VOB files. You can verify this with TV episode discs by selecting the Title that has all the episodes, then adding the individual episode Titles one at a time and watching to see if the output size changes in the lower part of the window, near the Quality % readout. If you select the title that contains alll the episodes first, selecting the Titles for each individual episode will not change the output size (or only very little).[QUOTE=Galaxy_Stranger;86989]One thing I've noticed for a lot of TV shows is that you may have one file per episode - and then another huge file with everything in it!
I believe they use this as a mechanism for "play all" vs playing individual episodes.
I've also seen movies have multiple copies on the DVD that aren't accessible through the DVD menu - one movie had the French release on it - all the titles and credits were all in French![/QUOTE]
