I get the clear Qam channels with my Sony HD Tv and with the HVR-1600 tuner card to get true digital over the cable I need a set top box from the cable company and it raises my bill by 15 dollars and another set of cables and such for the set up . I am not sure whether I am answering the question. I could get digital channels to if I pay for them which is another 15 dollars and yes they come through the same cable just a box that lets you receive then i believe. I think your USB tuner is the same basically as the HVR1600 I just installed my clear Qam channels are as clear as the TV set get the signal. Plus I had to split the cable to both connections on the tuner card. I am new to the game also and have not played with them much but learning every day. Did you scan for digital chanels at set up mine did but did not find any because I do not have a box.
