have serious doubts that this has anything to do with the problem. The problem is with the samsung
tuner 2121P30A and the ivtv driver. There have been several discussions about this on this list
but I don't believe a workable solution has been found yet.

I haven't heard anything back on this: maybe it's because I posted it
on Sunday night, or maybe I was too wordy. In any case, I'm going to
try again with a shorter version:
I think I'm doing everything right, and yet I still can't tune into
most channels using my PVR 500 card on my amd64 gentoo
system--everything is filled with static. Has anyone else seen this
problem?
Details below. Thanks!
