Only 2 Channels With PVR-350

This is my first attempt at building a PVR, and I've hit a wall. I put a
PVR-350 into a older machine (P4 1.8ghz with 512mg), plugged my cable into
the 350 coax input, and the hooked the box up to my router. I then ran a
KnoppMyth install (R5A30). The install appeared to go smooth. The listings
downloaded, DB filled up, frontend started, etc. Everything appears to be
working great, with one BIG exception: I only get 2 channels, 5 and 6 (local
CBS and CSPAN). The are coming from the cable, otherwise local CBS would be
on 3. But I get no other channels. Being as I'm new to this, and a relative
novice to Linux as well, I'm sure I'm missing some small, but key, step.

Any suggestions would be appreciated!

Thanks

It sounds like the tuner type might not be set correctly for the 350
card. If you run dmesg, post the output between the ==== IVTV begin
===== and === IVTV end ==== lines.

This is the output that I get. I'm not sure what I'm looking for, but
nothing looks obviously incorrect to me. Thanks!

Channels 5 & 6 are the magic channel numbers that almost always mean
you're using the wrong frequency table. My guess is that you've set
Myth to use standard (ntsc-cable), but you should be using HRC
(ntsc-cable-hrc)--although the exact opposite could be true. Change the
setting in mythtv-setup.

If, however, you got all channels except 5 & 6, you would be using
standard instead of IRC. If you get no channels, you'd be using HRC
instead of IRC or vice versa.

That was the problem. Thanks for the help. Until this weekend, I didn't
know that "harmonically related carriers" existed ;)
