Recently the danish DR DVB-T changed some of their channels from mpeg2
to mpeg4. After this change I'm not able to play back new recordings.
The sound is garbled and disappear after a while. The file plays back
fine in VLC.
I've played back other recordings with AAC without problems.

This is with 0.24.1 (can't get exact revision atm)

Here's the media info:
