I've noticed I have to turn up my white level four or five notches (a lot) from "Avia disc setting" when watching ABC HD (dramas and comedies alike). If I don't, everyone's dark hair looks like one single mass as all detail is lost in dark areas.
I can't comment on CBS or NBC because my locals aren't sending HD out.
I agree, I find *most* HD programming very dark... Using a Samsung ts-160 connected to Tosh 50H82, and I've currently got my contrast jacked up 7 notches above avia calibrated DVD settings, brightness above optimal setting (i.e. the blacks are so crushed that I'm settling for a dark grey trying to pull the details out in dark scenes), but I still can't get the screen to "pop" like I'd expect on indoor scenes. Most nature shows et al on PBS or HDnet look fine, but network programming is dissapointing thus far.
It would be great if the PBS stations (or HDnet) would go "back to the future" and broadcast Avia-like test patterns when they're off the air (or latenight in HDnet's case).
