Just subscribed digital cable with 4 HD channels. (Comcast in NJ if you wonder) I found the HBOHD/ShowtimeHD are darker than ABCHD/NBCHD. All HD channels are darker than the films played from DVD. Is my perceiption correct? Question: How do you guys calibrate the HDTV set on 1080i input? I have both AVIA and VE, but they are only good on feeding 480i/480p from DVD player to the TV. Now if I use the 480p AVIA calibrated settings, the HD 1080i picture looks much worse than DVD's 480p because the contrast and darkness are off the mark greatly. But if I turn up the brightness and other settings, the 1080i contents are much better. The TV set is Sony 61HS10, since 2000. The box provided by Comcast is Motorola 5100. Thanks in advance!!!
