Mah,
I tried the high brightness setting for the first time last night after your post. I thought I might go back and forth between the two depending on the circumstances. Superbowl party, for instance, would use the high brightness. Unfortunately, in addition to the inconvenience of getting a stepladder out to get up to the projector, the mount is not secure enough to stay aligned when I push the button. I decided to go back to high contrast and lock down the mount as best I could. I have total control of lighting, which is indirect, a high gain screen, and my walls are a dark finish as well. I think it will work out allright for me.
The question about a hint of green is something I'm still trying to sort out. I think the settings in lovingdvd's post look pretty good. Still, there is so much variation between sources and movies that I would go crazy trying to get the "perfect" balance. Some films have a hint of green, while others make people look sunburned. I have dish and cable (both SD) currently, and switching between the two on the same show the settings seemed like they needed adjustment. I don't want to spend ALL my time tweaking the picture. I think the best thing for me is to get the balance in the middle and just enjoy the movies. This projector is such a huge improvement over my lcd that it shouldn't be too difficult.

PS Mikebaby, has yours arrived?
