I woul dbe interested to see how well it plays hdpvr files.  My revos
*absolutely cannot* play them with 256 allocated (with vdpau slim -
that's all I ever use since high framerate content will severely jerk
otherwise)..

If it will play them ok with the extra cpu core I may get more dual
core versions..
