[mythtv-users] pvr 350 not able to record TV

[sarvinc at fastmail.fm]

I'm on a Athlon 64 w Gentoo and a PVR 350 card. Right now I'm using a separate 
video card for video output on an LCD monitor. I've got a coaxial cable 
plugged into the back of the PVR 350. When using "cat /dev/video0 > test.mpg" 
I get an empty file. I've tried searching the mailing list, googling, various 
setup procedures found on the net, and just different values but no luck. I'm 
not sure what's wrong and any help would be appreciated. I'm posting what I 
think is relevant dmesg output:
