I own the InFocus SP5000, a 720p projector. I also own the Sony PDP-300. My Infocus has a M1 (some version of DVI). I bought the HDMI to M1 DVI adaptor. I plugged it in. My blu-ray player froze. I couldn't do anything, not even turn it off. It just stayed frozen in my setup menu. I unplugged it, went back to the Components, and it worked fine. I plugged the HDMI cable in again...it froze, again. Has anyone else experienced this?
