I am adding a Tivo XL to my home. I have a Series 3 now that I am moving from my home theater to the living room. It has a lot of programs on it I still want to watch in the Home Theater. I thought I read somewhere that one Tivo could connect to another and play it's files. Is this true? Or specifically, can my Series 3 and XL do it? If they can how do you set it up? Thanks!
