I have an MPEG2 file recorded from an Australian DVB-T broadcast. When 
running ffmpeg -i on it this is what I get:
ffmpeg version 0.4.9-pre1, build 4723, Copyright (c) 2000-2004 Fabrice 
  built on Sep  7 2005 17:43:26, gcc: 3.2.3 (mingw special 20030504-1)
Input #0, mpeg, from 'd:\testmedia\Avril Lavigne test 2.MPG':
  Duration: 577014:01:50.9, bitrate: N/A
  Stream #0.0: Video: mpeg2video, 720x576, 25.00 fps
Must supply at least one output file

As you can see the audio stream is not identified, I know this is not 
the latest build, but if I am not mistaken not much has changed with 
regard ot mpeg2 and I tested also MPlayer and latest release of VLC and 
both of them fail to play the audio. Mplayer Classic on the other hand 
(as well as Windows Media Player or any other directshow based player) 
can play the audio just fine.
If you would like you can download a sample from:

Any suggestions or ideas with regard to what causing this and/or how it 
can be fixed are welcome,
