[mythtv-users] Default Audio Track for Internal Player

[Aaron]

FWIW, mine started exhibiting similar behavior as of late. My kids put
in the Chronicles of Narnia DVD, and the directors commentary started
playing. When I took a look at the audio streams, it said it was
playing the DD5.1 stream,  I switched the audio stream to the "2
channel" the receiver switched to Dolby Digital, and started playing
the 5.1 stream... It seems it was backwards. It used to be fine, this
is a recent change. My kids watch this DVD all the time.

I just checked our Fantastic 4 DVD, and it did the exact same thing.
