Hi everyone.
Just in case i think that the below method might work for you too as it worked for me.]
You know that regular cheap Pci capture cards are not ideal. Especially if you use built-in tuner you can experience some artifacts/noise that (vertical/horizontal lines, etc...) that do NOT come from your cable provider but from card itself.
I've had quality problems with 2 cars: AverMedia and FlyVideo 2000.
Both cards produced vertical lines expecially on low frequencies (below 80mhz). I did the following which got rid of these artifacts as well as improved quality A LOT. I woldn't believe that 60$ tv-tuner can produce such quality.
The method is very simple. You just need a regular foil to cover the whole card like putting it into the beg. But since foil is electrically conducive - you need to put a foil sheet into paper sheet FROM BOTH SIDES. Than just cover TV-card with this 3-layer sheet the whole card, and dont' forget to connect a foil cornet to a ground - like metal case. This will protect from any radio interfearence which cause by other computer's hardware.
It's a pity i cant post pictures of all of this. I actually got some pics. I just don't have my web space to put them.
Another thing, which can reduce noise, - is to moving TV-card to the bottom of the computer case - make it last pci card - this will also slightly reduce noise.
NOTE. If anyone tries to do it - it is very very important, as i said before - you must put foil into a paper sheet (better 2 or 3 paper sheets from both sides. Otherwice foil can cause short circuit Inside the card of otutside card with another hardware.
If anyone is interested in pictures - tell me how to put them.
P.S.I tested this method with my 2 card on different computers and it really helped.
P.S.2 This method helps to solve problems with mostly any "vertical/horizontal lines" artifacts and other similair artifacts. If your tv-card is "moothed out" or has "rainy" effect - I'm not sure this method will help.
P.S.3 In some cases particular hardware affects tuner quality more than another. For example, in my secnd computer, Fly video "doesn't like" a Scsi card near it. So i put them as far one from another as possible. Just for experiment, if i put them together (so that tuner box itself is near scsi card) i have strong distortion on all of tv-channels.
