I've been an enthusiastic user of Tivo's Comcast On-Demand offering in SF area, and just noticed today that the browsing interface has been updated from a Low-Def (old UI) style to an HD new style interface. Also while viewing a program, the progress bar is now HD style rather than SD style. I did notice more weird error messages when entering the On Demand menus than before, so maybe this is still a work in progress. Also noticed a glitch where sometimes when scrolling up/down a list after using page up/down commands, the scroll location resets itself back to the top of the list. Annoying when navigating some of the long lists. But upside is you can see a lot more characters of each program and get a side-screen that shows a short description without clicking on the programs, so its a big win. Also it seemed to me that the scrolling FFW/RRW is smoother with the new system, although the lag on commands is still about the same. Transitioning into OnDemand still switches resolutions back down to SD and then back up to HD based on the "Please Wait" bug. My version is reporting 220.127.116.11 and its a 4-tuner model.
