Hello all...I have had my Tivo HD for a bit more than a week now and I must admit to being a bit amazed at how slow the guide is. I have it set to "grid" mode instead of the way it is set up out of the box. When I navigate around the guide it just seems that it takes two seconds to move from what channel/page to another. Very slow! I've seen people reference a potential software fix (v 8.3?) in the future for Tivo HD but I just want to make sure that everyone experiences this and not just me.
