Subs of NTSC dvd out of sync with doitfast4u - the Big 3

[Talayero]

Hi

This is the first ntsc dvd I back up with the Big 3.

I used doitfast4u with autodetect NTSC video type enabled, the automatic way, I think, when you can see the magnifying glass icon.
Well, everithing went OK, but the authored dvd has the subs progressively out of sync.

Thanks if someone can help.

Well, I solved this issue by ripping again the subtitles with Subrip and load them into Scenarist, after deleting the ones that were imported by the script.
