I don't know anything specific about PS3 internals, i'm guessing  
along with everyone else.  I do know that it implements a hypervisor,  
that code runs under it and generally doesn't access hardware  
directly, and I do know that the XBox 360 does it similarly (the  
Microsoft XNA environment doesn't allow you to write code that is not  
managed by the hypervisor, iirc).  If Sony releases a way for  
"homebrew" developers to write code that runs under GameOS, it would  
be interesting to see how they do video (since they'll also likely  
run under the hypervisor).

I snarfed my PS3 mainly as a relatively inexpensive way to explore  
the Cell SDK (and I can do this via ssh), but it would be nice to be  
able to have nice, fast video when running Linux, so I wouldn't have  
to reboot into GameOS just to play a movie :-)

Regards,

John
