After some more playing, I reproduced it when playing back an xvid. I 
had to skip back and forth like a madman to get it to crash though. I 
couldn't do that with an x264 encode.

However, if I ran either the xvid or the x264 through gdb, they crash 
instantly with the same gdb error as previously posted. Here's valgrind 
output for the vc1 stream:
