I could on my old 9800 ll-in-wonder but the only slot the HD 4850 has is different from the 9800. Does this mean that I can't use my GC to watch TV from my comp or do I have to buy a special cable or what?
You could also just get a video capture card, but the standard graphics card nowadays does not have VIVO options so you need an intput of some kind to be able to watch an external video source.
