I might be losing my mind, but I've come across something this week that just seems off to me. I was setting up an HK receiver for someone and hooked up a typical Comcast Motorola cable box and a simple 0.5lb DTV converter. Both were being hooked up because apparently there are a couple of DTV channels not available from Comcast that his wife likes. In any case, the cable box is running component to the AVR and the DTV converter running composite (only option). The cable box is set to output 1080 with the 480 override off and the DTV only outputs in 480i. I swear, the picture from the DTV box is crisper than the SD channels via the cable box. I tried HDMI from the cable box, messed with settings, still looks worst. I don't get it. How can an over-the-air transmission being sent over composite look better than a cable transmission sent via component?
