I am trying to rip subtitles from the movie A Beautiful Mind, it is an American version, NTSC, 29.970 fps. After the rip is done, subtitles are out of sync, and not by frames, rather by the time code (could it be because of frames, or pulldown or something?) I am encoding with CCE. Still the timecode is not in sync even with the original VOBs. Could somebody please point out what could be wrong? Thank you.
