Recording HDTV takes almost no CPU, so if you can play back when not 
recording...

But, I won't stop you if you really want to set up an inferior video 
renderer.  (I won't help you either, as I don't/won't ever use XvMC.)  :)

You're either using (i.e. through falling back from unsupported) some 
non-Xv renderer or your card doesn't support Xv picture controls--like 
the NVIDIA 6x00 or above.
