anyone know why I have the green/purple bars on my HD channels?
Also, I'm thinking of going with the CableCARD (yes I know theres no Interactive abilities), but the TWC guy told me you can't get HDExtra with one. Is this true? Doesn't the HDExtra just require them to send a signal with the extra channels? I don't understand why they can't send the signal for HDExtra, he said that the STB can descramble it, but the CableCARD cannot. My TV has 8 VSB, ATSC, NTSC, and Clear QAM tuner, is this not good enough?
I've tried plugging the cable straight into the TV without a STB or a Card, and I pick up about 150 channels (about 80 are digital). I get HD Channels from 1.2 to 1.13. What good is the CableCARD then if he's telling me that it does no more than what the TV can already do??
