I recently purchased a Panasonic PT-AE7000U projector. This is the fourth projector I have had in my media room and I have always used an Xbox 360 there. The last projector I used was the Epson 8700UB and I had no issues. So with this new projector I am seeing video lag every couple minutes or so when watching HD-DVD's with my Xbox 360 addon. The framerate drops significantly and then returns to normal. The audio does not appear to go out of sync. I have never had this issue before. My configuration consists of a slim 360 connected to a Yamaha RX-V471 through HDMI which then connects to the projector through HDMI. The cables are Monoprice high-speed 24AWG with net jackets. This is not a long run. The cable between the 360 and the receiver is a couple feet and the cable to the projector is 6 feet. The 360 is set to output at 1080p. I eliminated the possibility that I received a faulty projector by exchanging the unit. It did not make any difference for this issue. Has anyone else had any similar issues? Does anyone have any suggestions?
