Re: Question on DVD obfuscation

OK, so ripping Chappaquiddick was a snap. Loaded disk, started VLC and it always plays Title 55. Start MakeMKV and Open the disc and the edited log is below. Title 55 shows a length of 1:46:29, and only 6 valid titles show in the main window after the disc open is complete. Out of those only 1 has a length of 1:46:29 when I select through them. Ripped that title and did a quick compare using "Jump to Specific Time" and again it's the correct movie.
One question though - In the Title Information screen when I select the correct title what does "Source title ID: 48" mean? Is this a different title than the info VLC shows as Title 55? The log has Title 48 and it has the same 1:46:29 length so it's confusing ...
This is the Title Information when I select the only title with duration 1:46:48 which is what matches the above Title #55 which is what VLC plays.
