I am using Digita Video Essentials disk to calibrate my TV, a Samsung LN-S4095D (40", LCD).

The DVD player is Oppo 980H, feeding the Sammy in 1080p.

The settings I get to, following the instructions, seems not to be good for both the DVD and cablebox feed, although the STB ( a Motorola from Comcast) is connected to the TV via HDMI as well and is delivering 1080i.

The picture seems a bit too dark when the same settings are used for the STB feed in high def ( and even darker for 4:3 programs, but I think that's OK, given the reduced light output associated with the 3:4 aspect ratio).

Could it be that the DVD player or the STB are not following the standards or, most probably, I'm doing something wrong...

All Oppo settings are on default or off, same for the TV (no DNIe or Digital NR filter).

Any ideas?

Thank you,
Alex
