I have VOB files, but I don't want to use existing IFOs, 'cause I want to delete ad stuff from the main movie. I created my own menus and I ripped subtitles with SubRip, but in order to reauthor them in DVDLab, I need to demultiplex all my VOBs and multiplex them again with subtitles.

As I understand, I loose quality in this case. And as I understand, there already are subtitles in VOBs, I just can not use them without IFO.

Is there another way to keep only menus and subtitles in new DVD? I have already tried IFOEdit, but I didn't succeed in deleting all unnesessary stuff.

Any suggestions?
