I was the one having problems with the 300i, and I manage to get it
running with 2.6.12.5 and 20050627, but I'm having the same problems
as you, there's extreme blockyness and artifacts in audio and video. I
was starting to think than that may be reception problems, but  maybe
it isn't. The card is running ok in analog mode. I have tried to get
the card running in windows with pinnacle's software (which is utterly
cr**, btw) but it refuses to store the detected digital channels.

Are they (the artifacts) a known bug? is there a way to get the card
running correctly? Any help is appreciated.
