OK, so you have 720p. Nit that hard. Recordings with 1920x1080 would
be much harder.

I did not try it, I don't have such streams (and I don't have 2.4
GHz), but it seems to be the limit. But IIRC xvmc should do all the
work. Do not use xvmc for a test, maybe the hardware decode can't
handle such huge files and try normal xv. Take a look at the CPU
load.

Mplayer should use the CPU, X should not. Try xv for a change.

x264 is good for 2) and a very bad idea for 1). In fact, decoding
H.264 takes much more CPU power. By old 2.6 GHz Pentium wasn't able to
play 720p H.264 files. On the other hand, my new Core 2 Duo only uses
one Core and can decode the files with cpufreqd slowing down the CPU
to 1.5 GHz.

Harder.

I also bought a fancy LCD ... and a Core 2 Duo 6400 to use it.
