Man, this was a hard thing to track down, but its finally fixed.  It seems
I had an ethernet going bad. It struck me strange since XawTV worked
beautifully, but when starting VIC I had poor performance. Then I tried to
start VIC locally, this is where a DING went off in my head. I couldn't
start VIC without a multicast address which means its sending/receiving
information regardless if I am the only one in my room and looking at my
local stream.

I swapped NICs and the problem is gone. Hey, this is something you guys
can add to your FAQ, "If your video performance was once good, but starts
smearing, its an ethernet card going bad."

Big thanks for your help Bob Olson.
