ogm files

[Jason]

I have installed mplayer nomore than say 2 weeks ago, but it does not 
support ogm files.  Ogm file are a new type that some people are using 
to add extra info to compressed movies, like extra subtiles to anime.  
When I try to watch one mplayer freezes and top shows mplayer at like 
97% cpu usage.  Only once after repeatily trying did my system lock up.  
I would like to know if anyone else has been able to play these files 
with mplayer or anythhing else.Thanks,
Jason
