I also had problems using HDMI 4 - random drop outs and flashing - moving to HDMI 1 resolved that issue. I'm not sure if @RayP has had any issues in that regard. I think he uses that output with his Oppo for DV playback.
I do and still get them on occasions. I think it's down to a HDMI handshake issue. But I just turn off the TV and on again and it solves it. Difficult to give a precise set of instructions for others to reproduce it so I live with it.
