That stuff relates to the capture functions common to both PVR-250 and
PVR-350 -- it has the internal capacity to do simple spatial/temporal
filtering, but this shouldn't cause the effect described.  (Especially
if it appears only on the amd64 machine -- same recorded video?)

Is the video card different between your x86 and amd64 machines? 
Because, I'm really having a hard time seeing that the result of the
deinterlace could be different between processor architetures..
probably just coincidence?
