Hi Neil,
The problem seems to be that ffmpeg is reporting 'PCM_DVD' for this
audio track. That would be correct for 20 or 24 bits per sample but
your DVDs only have 16 bps. As far as I can tell, ffmpeg should
normally detect that and change the required codec to 'PCM_S16BE'.
At the moment I don't know why that isn't happening.
I can reproduce the problem so I've created ticket 11941
(http://code.mythtv.org/trac/ticket/11941) to track it.
Richard.
