I have cablevision HD cable service and using the coaxial cable output (trying both of the inputs on the card) from the cable box I have tried scanning for digital and analog channels on the PC. I have only managed to pick up 4 channels which seem to be the same SD signal with various levels of quality. That basically seems to be an output of the channel that is being shown on the cable box as I need to change channel manually on that.
What am I doing wrong here? I built my PC so I'm happy tinkering but I have spent so much time on this and made no progress - it's driving me nuts!!!!
Any tips? I'm hoping there's a DOH! moment that will make everything clear.
