mplayer parent process died unexpectedly, exceptionally slow decoding

[GoogleCodeExporter]

When I try to play a h264 file with mplayer/coreavc, it processes one frame per 
several 
seconds, but does not use anywhere near 100% cpu. This is the mplayer stdout I 
get:

Parent process 11368 died unexpectedly

I installed coreavc using the mplayer dshow method, with no errors. I've tried  
with -ao null, 
with no speedup (I thought it might be pulseaudio being tetchy.) Does anyone 
know what's 
going on?

I am finding a similar problem, although I find I get some playback for about
15-20seconds then crash.
