XBox has accelerated video driver in DirectFB (video overlay with YUV->RGB
conversion and scaling). Decoding 720x576 mpeg2 with xine-lib uses ~20% of
CPU power, another 10% is used to copy data around.

Memory is just enough for simple DirectFB player, even with no swap (I
use xineliboutput vdr-fbfe on diskless XBox). But for VDR and
software player RAM is definetely too small. Anyway, installing VDR to
XBox does not make much sense as one can't attach DVB cards to XBox,
so using separate server for cards (and VDR) is required.
