VOB current position is wrong
If you have a multi-chapter DVD image with several VOB files, the current position is wrong from the second file onwards: it includes the previous files lenght. So if the first file has 20 minutes, the second one starts playing from 0:00, but shows values from 20:00 and ends in 40:00 if it only has 20 minutes of video. Clicking on a specific position will put on the right position for the current file, but show the current position as X + previous files length. Going back 30s or front 30s fails because of this. Thanks, João!
