Tomorrow my new Toshiba HDTV-ready 16:9 is being delivered and boy am I excited. I've made sure to have my cable company scheduled to install an HD decoder tomorrow to accompany the digital cable I already subscribe to. However, I am confused about something and I am hoping someone here can help. The only video output choices from my Digital Cable box are composite and COAX. Obviously composite output to my TV thru the HD decoder's component video output would defeat the purpose of component video altogether. What I can't figure out is if the exact same thing is true with the COAX output. Seems to me that since the COAX is outputting both audio and video, there can only be one conductor carrying the video -- so that must just be composite video all over again. Am I missing something here, or is the advantage of component video output/HDTV totally negated by what comes out of the digital converter? While there is an optional S-Video port on the back of the converter, it isn't active. Seems to me at the very least, COMCAST should be changing out my digital box to one that supports S-VIDEO, if not component-video output, right? This is COMCAST in Maryland. Anyone have a similar issue? Thanks!
