I am having the same sounding issues with my Hauppague WinTV card.... My
PVR250 seems to be working fine, it's just the BTTV card that seems to
be having problems.
I am going to try and change the BTTV version I am running and see if
this makes any difference.

Anyone else having this annoying interference with (noname) bttv card?
I bought 2 of these cards (called TV-Capturer) with BT878A chips and
have placed one of them in my myth backend server (Dual PIII 550) and
one in a frontend system (Intel Dotstation) and both show the same
interference when viewing and/or recording TV (that is: only on the UHF
band, VHF is fine) there is on quite a few channels some serious
Broad horizontal white bands where the picture loses horizontal sync.
First I thought it might be the computer (tested it first in the Intel
machine) but after placing the other card in the myth backend server it
behaved in the same way.
The second front-end machine I set up (Asus Pundit) got a Pixelview card
in it, and looks almost the same as the TV-Capturer card but doesn't
have this problem.
Should I ditch these 'cheap' cards or might it be a module problem ?
I tried almost every sensible combination of tuner and card numbers but
to no avail. (tuner=5 and card=36 seems to work best, including working
IR support in the Intel machine, the backend needs no IR..)
I'm thinking of putting in PVR250(s) in the backend server but until
then, I'd like to experiment with these cards to get the setup right.
Anyhow I think the whole MythTV system is very promising!
What's missing is some simple step by step information how to setup a
'backend only' system.
