No, its with a 1.8GHz Core 2 Duo, but that is largely irrelevant. With
VDPAU and a co-operating nvidia graphics card, you can decode full HD
no problem, with close to zero CPU usage:

mplayer -v /tank/video/recordings/hd.bbc.co.uk/2011/03/12/16_50_rugby-wales=
-vs-ireland-2011-6-nations.0.ts

This is a 1440x1080 MPEG-4 AVC HD stream I captured over the weekend,
playing back using 1% CPU. I wouldn't have thought the CPU would have
that much effect on that.

Cheers
