I have a new Vizio TV (ATSC/QAM) that picks up 55 channels over the feed and I'm guessing most of these are coming across QAM. The channels on the tv are 86-1, 86-2, 103, 104, 400, 401, etc.
I just picked up a Hauppauge 1595 dual usb tuner for my Media Center (win 7 pro) and ran the channel scan and only pick up 15 channels. Of those 15, some of them come up and say "scrambled". The channels on the MPC come up labeled 83.14, 83.15, 28.1, 83.20, 83.8, etc.
Same cable plugged into either the TV or the Hauppauge. I have not tried WinTV8 that came with the tuner, but wondered if anyone has a fix for this. I would like the get the same 55 channels that I get on the Vizio on the MPC so that I can use Media Center to DVR for me.
