[mythtv-users] Channel tuning problem

I am in the USA receiving analog us-cable (time warner in northern Kentucky)
via a happauge 150 and a hauppage 250. I am running Myth .20 via MythDora on
a P4 2.4Ghz with 1GB RAM and an nVidia GeForce 6200 video card. My TV is a
Westinghouse LVM-37w3 1080p monitor connected via DVI.
I have one channel that is coming in really bad. All of the other channels
look great. You can see a screen capture of it at
http://www.bzinteractions.com/capture.jpg. The video is fuzzy and there are
these wide vibrating white lines on both vertical sides.
If I connect a cable ready TV to the same outlet I get a perfect picture on
this channel. The only thing unique about the channel is that it is a
premium channel (HBO) that is decoded for free by my apartment complex and
rebroadcast to all of the tenants.
I have tried fine-tuning the channel with the tools in mythweb, but
everything I do just makes it worse. Adding 3000 to the fine-tuning slot
makes it nothing but snow. I gradually reduced it to 1500, then 1000, then
500 etc. The closer I got to the channel (27) the better it got. So I went
to 26 and tried tuning UP, thinking perhaps the channel was being broadcast
slightly under 27Mhz. Everything under 27 looked worse than 27 did. So going
up makes it worse, and going down makes it worse.
Can anyone tell me what I am doing wrong?
