Sure ;)

This file is created by Haali's muxer (also used in the x264 app). And 
it only outputs the minimum fields for the file to be readable (and the 
aspect ratio in a wrong way...). The FFMPEG demuxer will only consider a 
file readable if it's ready to read a cluster. So here's a patch to test 
that when Haali's files are used.
