TW in Houston does, their new Digital Box / DVR has HDMI output (I believe it's the 8300 model...also a 120GB hd now). I paid $99 for a Belkin's gold double titanium alloy space ship technology plated HDMI cable at Fry's recently. I'm sure Monster Cable's version is like $200 bucks or something.
It looks great...but don't really know if the cable is helping it or not.
out of curiosity how can you tell? On the new HD/DVR it indicates that it's at 1080 resolutions. Is HDMI suppose to be higher? Not like my tv can handle higher...just curious.
