Advertisements Well, the Xfinity OnDemand didn't work for me last night on one of my boxes. I suspect the cable cards have to be completely paired for this to work. I have moved my cards around a bit as I've swapped/upgraded Tivo boxes and haven't re-paired all of them since the programming still worked. I've been afraid to call Comcast because of horror stories of them screwing up my billing or other pairings. I was able to browse the list and there really wasn't much that I wanted to view anyway, so I'll just forget about it.
