Comment (by stuartm):

 I'm re-closing this as "Won't Fix" instead of fixed. As Yeechang has
 pointed out this was a little different from the other 'wrong DVD track'
 tickets because it involves rips of DVDs without preserving the audio
 track metadata. It's therefore neither fixed nor fixable within MythTV.

 The suggestion of simply going with the first audio track or the first
 multi-channel audio just won't work, it can't work since many broadcast
 videos place AD or commentary tracks as the first track. Those tracks are
 also sometimes multi-channel and in several cases (e.g. Chuck Series 5
 DVDs) the commentary track is 5.1 while the main audio is stereo. The
 audio track auto-selection code exists because we used to just use the
 first track and that consistently resulted in the wrong audio being played
 for many.

 What I've recently implemented in Master (0.27pre) for videos and
 0.25/0.26 for DVDs is filtering of commentary (et al) tracks when
 performing auto-selection for containers where this information is stored.
 This has been tested as working with mpegts (broadcast) and DVDs, and in
 theory other containers such as Matroska should be supported so long as
 ffmpeg supports reading of those attributes.

 I would suggest re-ripping the DVDs in question to another more modern
 container with a ripping application that will preserve the metadata. Or
 failing that ISOs should work correctly.
