Odd problem with my Tivo Premiere. The HD menu option under the Help Menu is selected, and sometimes it "flashes" as if it wants to go to the HD Menu, but doesn't. The standard UI still persists, but once you select the options for HD Menus, it doesn't want to seem to "stick". I can go back and forth and select the option for HD menu, but it doesn't come on and the standard UI is still there. Under the Display Settings options, you can see the last three options for Improve Discovery Bar Recommendations, Customize Tivo Central Discovery Bar and Video Window, but you can't select them because it gives you that "wrong" TiVo sound. Connected to the TiVo Service successfully before, but after a certain number of times, it failed, even though it's on a network with a working connection and I received Error S02. I suspect it maybe the hard drive since this one is kind of loud. I can also see other recordings on the other TiVo box. Any other suggestions?
