I don't recommend the Dlink if you use 2000/XP.. it is problematic the least... I am planning to add Radio with RDS support for the Cinergy Card (which is German), but I highly doubt Brazil's Radio stations support RDS as of right now.. If I were you, I'd look at Radiator's page for a list of supported cards, search for prices and compare features and make a choice. The only card I have is the D-Link.. Some users have been using the Hauppauge USB, I don't know how they're powering it (I think it needs external power).. You can most likely post this same question in the hardware forums.. As far as I know, FP and CF both use Radiator, so who uses radio in those front-ends, has gone through the same issue of finding a compatible card, and could give you some advice. I have an actual Radio in the Car (I use for Radio and AMP).
