Ok, I got my Avermedia TV Studio card yesterday and had enough time to play around with it.
It has few major problems: the software is faulty, after about 1 minute it changes channel by itself to something else. I reinstalled software about 10 times and I still get the same thing. Same thing with radio, the sound just disappears and that it. You have to switch back to TV and then back to radio to get the sound back.
I downloaded drivers from avermedia web site, but i still get the same problem. Please note that it might be because of my windows, I have Win XP + SP1.
Qualty is Ok, but could be better. Card was released quite a while ago, so probably it has something to do with it.
The remote control isn't working at all, so that is a good reason to RMA the card. I'm getting MSI TV Anywhere instead, because it has Mpeg 4 capture features and I think that quality will be better.
