A few days ago our Tivo Premiere updated to the new HD UI. I like that it's faster now... hate that Live TV PiP squackbox and wish I could turn it off. Well, today I got my wish. After a show ended I returned to the menu system only to find that the display was complete scrambled -- just little irregular blue and white cubes that fluttered around -- completely unreadable. After fumbling around for a few minutes and getting nowhere, my only option was to reboot. After rebooting, I was greeted by a shiny new Series 3 UI. That's right, Series 3, not the original Premiere UI, nor the new HD one... the one that has never been on this box before. Sigh. Suggestions?
