Good point on the help: I did something very stupid. Hopefully I'll get v2.16 out today with a fix for that.

What bitrate to the MP3s in your videos have? There's a feature now that if it's MP3 encoded audio and the bitrate is less than, or equal to, that copy the stream rather than re-encoding.

Can you put one of the videos in question somewhere? How long does it take to get out-of-sync?

Thanks in advance,

Andrew
