Comment (by ssd.mtv@…):

 I tried to copy the audio out of the videos and this is what I get from
 after:

 Input #0, nuv, from 'after.nuv':
   Duration: 00:07:29.03, start: 41411.301000, bitrate: 1411 kb/s
     Stream #0.0: Video: nuv, yuv420p, 1920x1088, PAR 136:135 DAR 16:9,
 29.97 fps, 29.97 tbr, 1k tbn
     Stream #0.1: Audio: mp3, 48000 Hz, stereo, s16p, 1411 kb/s
 Output #0, mp3, to 'after.mp3':
   Metadata:
     TSSE            : Lavf54.20.4
     Stream #0.0: Audio: libmp3lame, 48000 Hz, stereo, 1411 kb/s
 Stream mapping:
   Stream #0:1 -> #0:0 (copy)

 I think it is safe to say that mythtranscode is not merely selecting the
 wrong audio track, but actually creating new empty track.

 The audio tracks from before extract as:
 948K    before1.ac3
 1.1M    before2.ac3
