I bought an ATI ALL-IN-WONDER 2006 Editon PCI-E. In the manual it says that it is DVB-T compatable but i cant find anything but SD channels with it. My antenna is working because i was just watching tv with it, but on my PC its not.
Not quite sure what yuou mean? Are you tring to get HDTV channels? For that you will need something like the Ati HDTV wonder http://www.ati.com/products/hdtvwonder/index.html
