[mythtv-users] Mytharchive fails to detect audio stream.

I'm trying to use MythArchive (really for the first time) I have some
HD programming I'd like to save to archive to dvd.  The programs
playback fine in myth.

this is a file I used mythtranscode on a while ago (on a pre 0.20 svn
release) to cut the commercials out.  I checked the resulting file in
mplayer and it works fine.

my ffmpeg has a52 compiled as an option.   I am running the archive on
a slave backend I use only for commflagging and transcoding.  it's an
AMD64 machine, and the only oddity is that I would get errors
compiling myth with dts enabled so I disabled that in the build.

I included the output from mplayer, and the log files from mytharcive.
 Any help is appreciated.  thanks.

Info from mplayer on the file:
