talking about "'special' (non-coaxiol) cable has to run from the wall to the cable box to get an HD picture" but It could be special for your area for all I know. As long as your cable box is HD capable that should suffice.
Component adds up to an analog signal from a digital source to a digital receiver(e.g. your tv) that displays the HD picture. Theoretically some signal loss or interference can happen.
DVI is digital source sends digital signal to digital receiver (your tv)
In the first 2 cases you don't get a sound signal.
HDMI carries both a digital video signal and a true digital audio (with discrete 5.1 audio) signal.
you can get DVI to HDMI adapters but obviously you would make 2 connections - both DVI and Digital audio cables - to the one HDMI connector.
I think I got that right but anyone want to double check me on this ?

I recently bought a Sharp Aquos HD-ready LCD TV. The TV installer claims that a 'special' (non-coaxiol) cable has to run from the wall to the cable box to get an HD picture. I think they are wrong, and that only the cable box to TV connection needs to be with a "special" cable.
1) Who is right?
2) Which "special" cable should I use--DVI, component, or HDMI?
3) What if the TV has a HDMI connector but the cable box only has a DVI connector?
Thanks!
