I set up the following in Playback Profiles (3/9)

Current video playback profile: xvmc-vld
if rez > 0 0 & <= 1920 1088 -> XvMC-vld & XvMC

under EDIT

Decoder is: VIA XvMC
Video Renderer is: xvmc-blit
ISD Renderer is: chromakey
ISD Fade is: checked
Primary Deinterlacer: Bob (2x)
Fallback Deinterlacer: None

And I got the following error and a blank screen before I killed the 
mythfrontend process:
