I'm trying to convert a divx film to dvd and at the same time include subtitles for the film. I have the subtitles file (.srt using direct vobsub) but when I encode it using Tmpgenc the subtitles starting coming in too early, they also seem to get progressively worse. I'm converting from 23.976 to 29.97 using 3:2 pulldown, not sure if this will affect it?

any help or ideas would be greatly appreciated
