Is it possible to adjust the timing of subtitles without ripping and re-encoding??? Halfway through a movie the subtitles are off by 5 secs. Can I edit/delay the substream without going through the whole rigamorole again, using IFOdit or any of the numerous sub tools out there? i just spent three days making the subs work in the movie and don't want to re-encode again. and again, and again...
