It's usually the poor performance of the scalers in the HD converter boxes that causes the SD channels to looks so bad. Have your parents check the manual for the converter box to see if there's a setting for outputting the SD channels at 480...that should minimize the PQ issues on the standard definition channels. But it won't do much for the HD channels when they're broadcasting upconverted (non-HD) programs. The best solution is to split the incoming cable signal; one feed goes to the TV's onboard NTSC tuner and the other goes to the converter box. Then it's just a matter of switching inputs on the TV, depending on whether you want to watch SD or HD programming.

HD programming looks fantastic, but the picture quality has degraded on non-HD programming, noticably. The TW rep came out and blamed the fuzziness on the tv (which works fantasitically when the HD box is removed from the lineup and connecting directly to the cable, or with the old digital box). Dad is fed up and wants to go back to the digital box, especially since the HD programming is limited anyway. Is there somthing we are missing here? |
