I just recently bought the Tivo HD and have noticed the following in the Now Playing List. When I go to a show description, I used to (in the Series2) be able to use the Page Up/Dn buttons to advance through the show descriptions without having to go back to the Now Playing List. In the Tivo HD, there are no Page Up/Dn arrows on the screen, so I have to exit the show description and then select the next show to see its description. I tried searching the forums and couldn't find any info on this. Is this 'normal' behavior on the tivo HD? Thanks.
