Thanks. I tried various experiments with the RS40. I took two very thick high end 3ft hdmi cables that I had and placed them from the player to the darbee, and from the darbe to the projector. The picture plays fine for a few seconds to several seconds and then loses the signal very briefly and does another hand shake. It eventually cause my projector to lock up.
so I think the RS40 can't handle the darbee, even after I updated the RS40 firmware to the latest. Or my darbee is defective, but it works fine with my lcd tv and using the same blu-ray player. I brought it up just to see if that was the issue.
