It depends on what exactly you are trying to do. You can obviously get the local channels or over the air channels but I am sure its a software setting if they are coming in clean on a TV and not on the PC. I have the ATI All In Wonder Pro, its a few years old but still works fantastic. For satellite input, you will not be able to use the TV guide software unless they have updated it but run a splitter from your satellite box (one to the TV and the other to the computer) and just have it come in on the AV input and you can switch the video modes for recording/watching stuff on satellite vs over the air or if you get local channels on your satellite then you only need the one input.
