Here's my problem:  I'm recording my local CBS affiliate (KOIN 1080i)
and when I record it from MythTV the audio is garbled (both from
MythTV and mplayer) then upon the completion of the recording, the
backend crashes, but when I record it by tuning using azap -r,
then cat'ting /dev/dvb/adapter0/dvr0 I get a clean file with no audio

I'll put as much relevant information as I can think of:

First, the mythtv info:
Here is a one minute snippet of the channel

Here's some info from the log file when it tuned to the station:

Now for the file that I recorded using azap:
Here's the file: http://sturgeonfamily.org/files/KOIN-HD.mpg (19.3 Mbytes)
and the tuning info from .azap/channels.conf

The only difference I see is that in mythtv, it seems to want to pull
both audio channels (english and spanish) in. and in my channels.conf
file, I only specify one audio channel.

Any help would be greatly appreciated.
