SD is SD, and a lot of the content of standard cable is analog-
sourced, even if it's coming to you via digital cable. Throw it onto a
large HD screen and it looks grainy and noisy because it *is* grainy
and noisy.

A cable box without even s-video outputs is wholly unworthy of your
TV. The composite output is taking what little is there and making it
worse by combining every component of the video signal onto one wire.
No upconversion is going to help with that.

No flame intended, but I'll never understand people who will spend
thousands on equipment and then refuse to pay the small change it
takes to provide a proper signal to it. You need HD cable.
