I have an Elite with the latest software. I use the SDUI. Two problems I have noticed. 1. When I press tivo-2 to bring up the todo list, sometimes it will stay for a few seconds and then jump randomly to a later day. You can't go back to the current day from that screen. 2. Sometimes the menu will lock up and the TiVo will not respond to the remote. If it is recording something, it continues recording. After a few minutes the screen will unlock and then behave normally.
