After testing early Freeview HD support with MythTV, on some recordings on
audio would stop partway through the recording. This typically happens on
program start/end and the following error is reported:
[aac_latm @ 0xf13bc0]channel element 0.0 is not allocated
Using a recorded file, both VLC and Mplayer exhibit the same problem,
which indicates FFMpeg as the likely source. What appears to happen is
there is a change in audio configuration in some of the streams from
stereo to six speakers and back again. FFMpeg can decode both
configurations fine, but fails if a transition occurs mid-stream.
I've posted a 50MB clip that exhibits the problem at:

The audio decodes fine for the first three quarters of the clip, and then
fails when the program starts.
