Well, I for one agree with you.  The encoding from the PVR card (a 250 
in my case) is inferior to the source material, even using S-video from 
the DirecTV box.  One problem in particular is the apparent lack of 
luminance AGC in the tuner.  On a normal TV this is done in hardware (or 
maybe software in newer TVs) but it seems to be missing from the 
hardware/software of the 250.  The result is that scenes, particularly 
lettering, on a mostly white screen get washed out.
