Exactly what models of equipment do you have? (display device, AVR, computer, graphics chipset, editing software).
People with experience with those particular products might have specific suggestions.
My guess would be that the problems you're seeing most likely are the results of buggy laptop software, HDMI drivers or firmware.
HDMI/HDCP interoperability is still a black art, and manufacturers are constantly making updates to support them better. Make sure you have up-to-date firmware in the projector and AVR, in addition to current versions of the BIOS, graphics drivers and software used in the computer.
For testing and initial development, I suggest using a 6-12 ft HDMI cable to connect the laptop directly to an inexpensive LCD TV. In addition to helping locate the source of the problems you're currently seeing, it would reduce the number of hours you burn on the projector's rather expensive illumination source. HD TVs are available for less than the cost of a new projector lamp.
