Some more playing around confirms that I can watch livetv on the xbox
frontend using the analog tuner (PVR-250) no problem.  This problem only
happens with the digital tuner (HD-3000).  I only get 1 ringbuffer file for
the analog tuner created, and the frontend log reads:

Frontend is xbox xfedora using myth FC4 packages from ATRPMS; backend is FC3
with packages from ATRPMS.  Both are running current build (0.19-124).

Thanks for any advice.
