I think the problem you are seeing is because the Myth audio and video are
slightly out of sync. Editing and transcoding the file without first fixing
the sync error makes this worse.

You need to do a lossless transcode first before converting to h264.
Something like:

/usr/bin/mythtranscode --showprogress --honorcutlist --mpeg2 -c channelid -s
starttime -o outfile.mpg

I have a python script that converts files to h264. It does commercial
cutting and a lossless transcode first. I run it as a user job. I can pt it
up on github if you think it might be useful.


Ian.
