The answer may be obvious, but seeing as how I cannot find an explicit answer anywhere else, I thought I would ask here.
How good of a video card do you need to watch TV on your computer?
I'm not talking about minimum system requirements. I mean to get a decent moving picture on your full screen (desktop or laptop), would you need a dedicated video card? Or would the Intel x3100, or ATI 1150 be enough to do the job? (Let's assume the computer is at least a Celeron/Sempron with 1GB memory)
