That's correct. There's really no point to using XvMC on a typical
desktop machine, as the CPU has plenty of power to decode SD MPEG-2.
As an aside, XvMC is a really horrible interface to use to build a
decoder. I've written several gstreamer elements for hardware decoders
before, creating one with XvMC would be like poking my eye repeatedly
with a sharp stick.
