Mythtv ignores audio tracks

Description
After I upgraded from svn 9759 to 9953, mythtranscode can't find the audio tracks in certain recordings, and as a result drops all of the audio.
I've attached logs from the following:
mythtranscode -v audio -p autodetect -i 1321_20060515194800.mpg -o /hdtv2/tmp/out.mpg
If there's anything else I can provide, let me know.

This started in svn 9820. It happens when transcoding or watching the recordings in mythfrontend.
I looked through the changes in 9820 and 9825 but I'm clueless as to how to work around this. Anyone have any ideas?

I need a sample recording to debug this. Please reopen when one is available for download.

I've had the same problem. As posted by Bill Cizek on -dev, the following change fixes the problem:

btw, if you want a sample that this happens with, send me an email and I'll put a "small" (10 minute) mpg on my web server (it's slow for upstream, but.... )
For some reason, with me, the problem only occurs if mythtranscode -m is run via the FE.. twice. I can run it over and over and over via CLI, and I have no problem.

Patch would significantly slow down channel changes. As the previous comment said, I need a sample to properly debug things.
Good transcode
