I just got set up with my TivoHD. Verizon Fios just left after "installing" the 2 cable cards. Looks freaking awesome. A hell of an upgrade from my S1 from 2000. Something new i've noticed. Whenever I turn the TV on or change the channel from an HD to an SD channel (or vice versa), I see a message pop on screen for about a second. It says. HDMI Cable Not Permitted (press select for more info). If I catch it in time and press select, a screen pops up and says something about that the TV doesnt support DRM video and that I have to use component video. I have a Samsung LN-T4065F. Weird that it shows and disappears. Right? On a side note. When I'm on the SD channel for NBC it scales the image to fill the screen when set to FULL. But when I goto the HD channel for NBC, It doesn't scale no matter what ASPECT is set to.
