It does.

The big issue w/ATSC OTA and cable is the encoding (8VSB vs. QAM), There's no 
encoding to deal with on NTSC, so the only meaningful difference w/NTSC is 
the frequency table.If one simply selects the us-cable freq table, the pcHDTV 
shouldn't have a problem with NTSC cable.

Hell no. :-)

25 miles here, but monster roof-top antenna, amplifier and RG6-QS. I get all 
the HD channels I care about (though two have issues...) and I believe all 
the SD channels are fine, but I haven't bothered looking at any of them in 
ages (I've got cable too).
