Has anyone experienced Subtitles freezing once a DVD is compiled, burnt and played?

When watching the movie the subtitles in a number of places will just freeze on particular sentences and will not progress. In order to get them working again, I have to rewind a fraction and then play.

I personally cant see anything that am doing wrong. Ive even checked the subtitle file itself to see if there are any errors in it but cannot find any.

The movie is NTSC and the subs timecode are written the realtime option within DVDLabPro.

Any pointers would be greatly appreciated.

cheers....


S'ok guys.... Subtitle Workshop found a load of errors and have fixed the problem.
