I took the plunge and picked up a TIVO HD last night at circuit city. I set it up this morning without cable cards (Cablevision requires a tech to come and do the install). I noticed a couple of issues/bugs. 1. When I change channels, there is a delay and occassionally (70% of the time) text along the bottom of the screen says searching for signal. After a second or two, the message disappears the station is tuned in. Any idea if this will go away after I get cable cards? Anyone else experiencing this issue? 2. When set to native, and pressing the TIVO button, the screen flutters a bit and gets real noisy before showing the TIVO menu. This does not happen if set to 1080i. Not sure if this is an HDMI issue or a TIVO issue. Anyone else out there with a similar problem?
