Weird.  I have only had problems with the frequencies below 100 MHz (I 
am unable
to confirm problems from 91.25 to 115.25 as I do not have any signals on cable
channels 95-99.)  I planned on experimenting with the board this weekend but
wound up not getting around to it.  :(

Also, anyone posting here needs to define the degree of the problem, i.e.
whether it is "there's a little static, I can notice it and i'm being picky",
or "so bad it's barely watchable" (Such as from the MPEG clips posted a 
week or
so ago which had the EXACT same symptoms on tuner 1 lowband that I 
did.)  After
living with OTA broadcast TV for three years, I don't notice mild static on
cable channels, as it's far better than what I used to have to deal with.

I'll admit, while I plan on experimenting this weekend, I'm sort of 
afraid to do
so since my card decided to start behaving properly for no apparent reason at
all 3-4 weeks ago.  :)  That's going to make this problem extra hard to 
solve -
intermittent problems or ones that fix themselves after a period of 
time are the
hardest ones to fix.  :(
