[mythtv-users] Cannot tune channels above 55

Apologies if this is a driver issue rather than a
MythTV issue, but I have been unable to tune channels
above 55.  55 itself is snowy, from 55-60, I get
reminents of Ch 55, and above 60, I get static.  My
setup is Fedora Core 3, Hauppauge PVR-500, and ivtv
0.4 driver.

I followed the instructions at
<http://wilsonet.com/mythtv/> to get everything up and
running, but found I had to add "options ivtv
tuner=57,57" to my modprobe.conf to get my tuner
recognized properly.  Everything works great except
for the 55+ problem mentioned above.  I'm in Fairfax,
VA, using Cox Baisc Extended analog cable and Zap2It
for listings.  I used us-cable as my frequency table,
though I've tried us-cable-hrc too.

Relevant modprobe.conf and dmesg sections are included
below.

Thanks,
Dan
