While it is built in, currently with MythTV you can only use the card as either a HDTV or a NTSC card, but not both.

I don't know about the Air2PC HD-5000, but the pcHDTV HD-3000 has a better tuner for QAM than the old Air2PC. > I'm likely to stay with cable, since my stations are in multiple > directions and my wife has already registered her disdain for a rotor. Depending on your distance from the stations a omni-directional antenna might work, and since UHF antennas are pretty small (mine is 1 ft long), you might be able to put up an antenna for each direction. > When I hear about cable, I hear about QAM.

The licenses for the 16-VSB patents are/were more expensive, and many cable operators were already using QAM-64 and QAM-256 for non-HDTV DTV by the time they started looking at HDTV. AOL-Time-Warner in New York was using VSB for a while, but I believe they have switched over to QAM now. > I've heard reports of both cards doing QAM, though the PCHDTV seems to > claim not to do it. What gives? The pcHDTV HD-3000 supports QAM. The HD-2000 hardware supported it, but my understanding is that the pcHDTV folks could not get licensed QAM firmware for the HD-2000 from the DSP chip maker. -- Daniel
