Comment (by swybo):

 That's my point actually, if you check the avi file in virtual dub you'll
 see D frames (delta frames) every 3 frames with no data in it. This is
 caused by a badly functionning encoder actually but VLC or virtual dub can
 read all frames in the video whereas ffplay, ffmpeg... can't find any
 frame other than the first one

 I thought this indicated some kind of issue in the AVI demuxer
