Don’t know, it’s an Athlon XP-M 3200, but as I said in response to
Steven up /\ there, the r280 chip in the Radeon 9250 has MPEG
decompression "assistance" for windows and the specks are known (hence
the OS driver) is it not possible the OS driver (& MythTV) might one day
make use of that feature offloading the CPU maybe even more than XvMC
and opening up the possibility of HDTV?
But I don’t know the nature of this "assistance" or whether this is
feasible or not.
Thanks.
