HD trivia/ramblings:
High Definition signals are only available through Component (separate R/G/B) connections or through DVI or HDMI connections. (look behind the set and see what's connnected). (e.g. Circuit City, Best Buy, Costco will probably be connected RGB. Target, Walmart will probably be connected F-Type (likely SD), not doing them justice for what the connected sets can really can do.)
OK, I'm gonna show some of my TV technology ignorance here. I don't even know what DVI, HDMI(although my DVD is hooked up with one),F-type, SD are. Does that mean that my two hdtv's are getting the hd channels someplace else besides the cable tv coax they are hooked to? I had trouble with one not getting the hd, until I found a splitter on the cable line hidden in the corner of my basement. I took it out, and now all works good. I went in to a store when I bought one of these with a wooden folding ruler to find one that would fit in the cabinet. The kid says, "what's that thing?" I said, "a stick of inches." "what?" "A folding ruler" "Oh. what's that for?" "So I make sure the TV I buy will fit in our cabinet." "Well put it away, the dimensions are here on the sticker." This was after I spent 10 minutes walking around measuring tv's. Man, I'm so lost when it comes to all this stuff.

Some diagrams... F-Type (Coax) - Typically Standard Definition (SD). HD Capable only for Over The Air ATSC (Digital) tuners)  Composite (Not HD, but Good SD, better than coax) S-Video (Not HD, but Better SD, better than composite) Component (HD Capable - Analog R/G/B, some say still the best) DVI (HD Capable - Digital Video, no audio - separate connections, becoming obsolete) HDMI (HD Capable - Combined Digital Video and Audio Signals, becoming the standard, obviating DVI) 2Suns, you could be getting HD on your TV through your cable box IF the cable box is hooked to your TV by Component, DVI or HDMI. If the box is connected to your TV by Coax, then I doubt your TV's are displaying HD. They might be playing HD channels 'downconverted' by your box to SD out of the coax line. If your cable box is HD capable, it will have component, DVI or HDMI output ports to connect an HD set to.

If your TV is displaying HD content direct from an incoming Cable, then the cable company is putting out a QAM digital signal that the TV's QAM capable digital tuner is decoding. Yes. That (QAM Digital Cable signal) can be HD content direct over Coax, no box required. Some still say Component is best for a few reasons: 1) Compatability. (There are still a few flavors (versions) of HDMI that some devices support and some don't). 2) Which device has the best D/A converter. If the TV has the best D/A converter/processing internally then maybe HDMI is the bet. If the external device has the best D/A converter processing, then component may be best. 3 Other thoughts: Cable length considerations, Copy Protections...  Not sure about Component being able or not to carry 1080p. Good question. Quick web search is mentioning the RCA connectors as the limitation. Thanks for pointing that out. Here something I just ran across related to cabling: http://www.audiolofftreport.com/dvi_hdmi.html
