raspbmc - mpeg4

[timl]

Hi, when I play a particular file with raspbmc I get the audio but no video. Do I need a plugin to play this?

[tim@winter ~]$ file synced.avi
synced.avi: RIFF (little-endian) data, AVI, 352 x 288, 25.00 fps, video: Microsoft MPEG-4 v2, audio: MPEG-1 Layer 3 (stereo, 44100 Hz)
[tim@winter ~]$

thanks
