I am a newbie regarding HTPC so please be gentle ;-) I am thinking of building an HTPC to go to a Hi-Def ready display. I was thinking of using a sweetspot RGB input capable capture card. To my surprise there is little information on those on this forum. Do people use it with Sky? And does it work well to upscale the image? Is the Xcard required? Some advice and/or pointers to other sources of information would be great!
