Sorry...been a long while since I played with this.

Anyhoo...was able to grab an srt file for the video. Watching in myth it
was terribly often off, e.g. person left the room and then their dialogue
would appear. I downloaded the Windows version of Subtitle Edit and when I
open the files on my desktop the audio and subtitles were perfectly synced.
I had done nothing. Why would they be off in Myth?

Just curious if SE does some autofixing when it loads. Don't have access to
the mythbox right now as the missus is asleep. Should I resave the .srt
file and check the myth in the morning?
