As others have mentioned, "graininess" may be coming from low
signal level or not enough bitrate on the encoding. I have long had
issues with the "softness" of my PVR-250 as compared to the tv's tuner.
After a rather involved investigation, I concluded that it appears to be
a limitation of the tuner card and/or driver. Anything over about 480x480
results in no measurable improvement in resolution.
