As far as I can tell, the LEDs on the front of the Tivo only tell what the Tivo's output format is. For example, I run in Fixed 1080i so that the TV doesn't flicker/switch modes whenever I switch between channels in different formats. Thus, regardless of what type of programming I'm watching, the front panel always says "Fixed 1080i". I know I could change this by switching to native mode, but I don't want to. How do I find out what format the program I'm watching is in? The guide data appears to be unreliable for OTA ATSC channels. For example, I can jump off a channel and then back onto it and the guide data changed from 480i to 720p. Doing it again and the channel changed back to 480i, all while the same program was playing. Finally, does anyone else think that it would be more useful if the front panel displayed the (source) program fromat rather than the output format? For me, I think mine is always going to display "Fixed 1080i".
