 After upgrading from 0.24 to 0.26 I have found that some recordings
 repeatably crash mythcommflag when trying to do advert detection. It seems
 to be correlated with recordings that come from the DVB cards, with the
 following profile according to ffmpeg:

 Input #0, mpegts, from '20992_20130227220000.mpg':
   Duration: 01:04:58.89, start: 29964.196356, bitrate: 1876 kb/s
   Program 1
     Stream #0:0[0x1a21]: Video: mpeg2video (Main) ([2][0][0][0] / 0x0002),
 yuv420p, 544x576 [SAR 32:17 DAR 16:9], 15000 kb/s, 25 fps, 25 tbr, 90k
 tbn, 50 tbc
     Stream #0:1[0x1a22](eng): Audio: mp2 ([4][0][0][0] / 0x0004), 48000
 Hz, stereo, s16, 128 kb/s
     Stream #0:2[0x1a23](eng): Audio: mp3 ([4][0][0][0] / 0x0004), 0
 channels, s16 (visual impaired)
     Stream #0:3[0x1a26](eng): Subtitle: dvb_subtitle ([6][0][0][0] /
 0x0006)
     Stream #0:4[0x1bb1]: Unknown: none ([11][0][0][0] / 0x000B)

 Files recorded prior to the upgrade, with the same ffmpeg profile will
 crash mythcommflag now, when they didn't under 0.24.

 Please note the correlation between the "codec MP3 has 0 channels" and the
 profile for the "visually impared" treack of "Audio: mp3 ([4][0][0][0] /
 0x0004), 0 channels, s16 (visual impaired)"

 I have attached a back trace from gdb and can forward a core file if
 needed.
