Because of the extensive video processing done internally at only the eight bit level, getting the 10HT optimized does require careful adjustment of gain and bias, using the color balance of the "warm" color temperature as a reference. The Don Munsil FAQ discusses some the issues and a genearl procedure fairly well. It also helps to have a DVD player or HTPC setup with gamma control, and use a test disk such as AVIA to set the brightness and contrast range, and then use gamma controls to optimize the gray scale steps.
You don't describe anyting about how you've gone about setting up your projector. I've certainly seen posterization on 10HT's, particularly if the RGB gain and bias setup isn't optimum, and if the grayscale steps aren't dialed in. This is a potential weakness in any digitial projector; in that regard, a misadjusted CRT projector may be less annoying, because misadjustment will only put the light levels off, but it won't shift too much of the light variation to just a few bits of resolution.
We can screw up the other planets later!
