I recently bought an ATI X1900 AIW Card which was around $300 I installed Vista Home Premium to use the Media Center feature. The TV Tuner part of the card won't work and I was told by ATI that there is not going to be a fix for any of their AIW cards but their TV Wonder Tuner Cards models 650, 550 and Elite will work under Vista. I had to go out and spend another $80 to use the Media Center. After all the months of development I cannot believe that a company like ATI cannot get their act together and make their products work with Vista.If I'd known about this beforehand i would have bought an nVidia Card instead! I'm not happy at all with ATI.
