Hi all, update regarding latest pvrxxx-20071304

Tunercard: pvr-350 , Tuner NTSC see dmesg below for details.

I replaced my aerial (possible interference issues) with a Cable-TV 
so far so good!, finally getting A/V on all 70 channels, (using 
...setchannel freq) with no errors in messages yet.
A/V is choppy though.

but its crappy( hard to explain really unless you see it, but the picture is 
cut in half, and the soound is choppy) -The pvr-350 is ok I checked it 
recently again in another box.
It seems its a "sync" issue with the my Tuner -but I'm just guessing here.

Sean, I'm curious is yours pvr500 and NTSC-tuner, or pvr350 ?, NTSC 
frequenciy settings should be standard anyway, obviously our tuners maybe 
different, -I must have an oddball.
