I have an FX5200 personal cinema that rivatv cannot seem to support (with the 7174HL chipset). I bought it because I understood nVidia supported Linux but I learnt subsequently that there was some small print to this claim! In the linux spirit i then became the webmaster for rivatv so that I could ensure a good "health warning" was available to other potential purchasers.
Needless to say I'd love to be able to remove the warning. With the best will in the world, it does not seem that rivatv are goingto get my card running anytime soon.
I'd be prepared to offer a little cash, but I guess 60 times just a little does not really buy programmer time.
