Ah...thanks for clearing that up.  I decided to do a little testing on
my 0.20.2 frontend (P4 3.0 Ghz w/hyperthreading enabled).

Watching 1080i HD content with bob, it appears that the 'Standard'
(ffmpeg) does use a bit more cpu than libmpeg2 that I've been
using...about 10% more overall...certainly acceptable, but it does
seem to use more.

I've been a little concerned with all the talk about extra CPU usage
in 0.21.  I have the CPU to spare for sure, but my frontend's fan
noise might start getting noticable if, for example, it went up by 15%
or more.

It won't stop me from upgrading though.
