Mike, I gave this a try yesterday to see how well it worked.  I was
mainly hoping fill mode auto-detection would work in this
configuration.  It didn't, AFAICT.  Anyway, progressive video worked
fine except for the noticeably and expected higher CPU usage.
Interlaced video had an annoying problem, however.  Whenever I skipped
position, there was a very noticable flicker between frames from
before and after the skip.  It looked like maybe decode and/or
presentation queue wasn't getting reset properly.  Have you seen
anything like that?
