I don't know any way to check this reliably.. But we could add
something to the release notes. I've heard the 8x.xx nVidia drivers
peg the CPU at 100% with XvMC, even if you don't use OpenGL vsync.

It depends on what you are watching, a 2.4Ghz HT machine can handle
most non-sports programs if you use the soft 'real-time' options in
the kernel. And the hyperthreading really does help. There are also
more factors than just the CPU speed. The memory bus speed and the
hard drive subsystem matter as well. The 2.8 Ghz recommendation is a
target for trouble free viewing. It also allows moderate time-stretch
on non-sports programs and 720p material. A 3.2Ghz or better machine
would probably allow you to use the level of time-stretch I use on my
ivtv recordings...
