I checked my recording profiles for my hdpvr, and all of them already had
the audio codec set to AC3. However, I checked the actual setting of the
audio_encoding parameter:

[root at scorpio ~]# v4l2-ctl -C audio_encoding
audio_encoding: 3

The 3 setting is for AAC, like you said was being recorded, so I'm thinking
maybe there is some sort of glitch where mythtv isn't setting the
audio_encoding parameter of the hdpvr driver properly based on the audio
codec in the recording profiles. I manually flipped the setting to 4 (AC3),
and now it seems to be working just fine, so at the very least I now have a
functional workaround.

Thanks for a nudge in the right direction!
