Edit: before I begin, let me say that the Roamio's UI is TiVo's best UI yet and I applaud their development effort for it. For me, it wouldn't take much to make it perfect for needs, and that's why I started this thread. I'll start off. 1. In the Premiere's SD UI, when I had multiple episodes of a show, I was able to use "Channel Up" and "Channel Down" in the episode description page to move between them. I was able to quickly see all description information update (episode number, airing date, duration, etc.) as I moved through the shows. The Roamio UI shows most of the information in the truncated summary on the right (which is clever design!), but not all of it. When I select a show to see the full description in the UI, I wish I could still use "Channel Up" and "Channel Down" to move between them. 2. Although the Roamio menus are impressively fast compared to the Premiere HD menus, there is still some lag before it completely renders all menu items. I noticed that if I move the selection cursor before the menu is finished rendering, it will force the cursor back to the original item when the menu render completes. To see this, go to My Shows, then find a list of episodes for a show. Go to the detailed information page for the first show. If you press "left" to to back to the episode list and immediately press "up" or "down" to move to another show, the cursor will be forced back to the original show if you beat the menu. Strangely, some shows redraw their menu very quickly and some do not.
