[mythtv-users] Transcoding switches audio tracks

I've had a problem with several recordings where transcoding switches 
the default audio track.  It's usually not a big deal to manually change 
it back, but I would like to fix it for one that we will be showing to 
our son multiple times.

I think I recall in the past losing the correct audio track altogether 
if I transcoded the show a second time, but I can't verify that.

The track that is being picked as the new default after transcoding is 
the descriptive audio.

This is on digital recordings from a HD Homerun, so it's the raw MPEG 
from the cable feed (on unencrypted channels).  We've only seen it on 
two channels, so it could be something with Fox and one of the PBS 
affiliates, but we don't record enough to have solid data (and it may be 
those are the only channels that we record that have the descriptive 
audio tracks).
