Caveman.... I do not subscribe to Comcast HD service but I do get a number of HD channels anyway. I bought a Samsung Plasma HDTV hooked up to standard Comcast CATV coming out of the wall. When I did a channel scan on the Samsung, it found about 15 HD channels (all the networks, PBS, HGTV, Golf Channel, Discovery HD, WB network, and a few others, but no ESPN). For instance, CBS is channel 6, HD CBS is 6-1; ABC is ch9, HD 9-1, Fox is 35-1). Apparently, samsung has a QAM tuner built into it that recognizes these "split" channels.

OK...that's how I get HD. When viewing any of these HD channels, I can get closed captioning with no problem (very crisp text too). Hope this helps you (or others who have Samsung or similar TVs with QAM tuner capability)
