Ah, I see. I have a PC hooked up to my TV, which I use for the purposes mentioned in my post. I (perhaps erroneously) took it for granted that most people using these programs were doing the same.

This is probably beside the point, but thinking back, XBMC made a lot of sense back in 2003 when it was released. It wasn't as feasible to a) have an entire spare PC and b) hook it up to the TV easily. I certainly didn't have HDMI or even VGA on my TV back then, only composite and maybe component analog video...
