Tivo's live guide is also way better than the Comcast DVR's guide. Specifically I used to have Moto DVR with iGuide software, and Comcast would periodically put up a line of ads blocking the bottom row of the guide, so the whole guide is just 4 lines tall. And since when it scrolls it scrolls a whole page, and the blocked channel is always blocked even if you scroll up or down a page, so it's very difficult to actually see the blocked channel. It's pretty frustrating when channel surfing. In Tivo's guide, every time you scroll a page, it puts the last line from the previous page on the top line of the new page (if you scroll down), and vise versa if you scroll up, so it's always easy to find your place when you're scrolling through the guide.
