Gave me a good idea....

I went in and change the DECODER to "STANDARD" and left the "RENDERER"
to VDPAU and from what I can see -- the decoding artifacts are gone...
I'll have to wait till I'm home in front of the machine, not relying
on x11vnc, but they appear to be gone... and when I switch back to
VDPAU decoder, they come back.

Running about 38-40% CPU playing 1080i NFL football
Changing back to VDPAU decode is 12% CPU, but artifacting.

maybe a compromise, just in time for superbowl.....
