We could correctly calibrate our HDTV's. When you buy an AVIA or other calibrating dvd and play it on your dvd player you are only calibrating for that particular input. It is costly to buy equipment capable of generating a HiDef Color Bars for calibrating HD. If we had a HiDef Color Bars on MOOV from 12-3AM we could better calibrate our HD inputs. You could play music. It wouldn't disturb any program and would not appear much different from other MOOV broadcasts.
