Well, I've found a program that will let me control a replaytv remotely via a PC. You can access the channel guide and schedule recordings as well as pull stuff off of it to watch on your PC. The guy writing it posted it in the avs forum. The file is called ReplayTVServer. I think there are a bunch of other programs that do the same thing though.

Is there anything like that for the Tivo?
