Interesting as I had the same thing happen to me yesterday. I have NEVER had anything but perfect video the entire time I've had my P4 but yesterday had exactly what you described; pixalization, blank screen, choppy video, etc. I chalked it up to quite a few other r/c planes in the air but never had that happen before. Hopefully this is one time occurrence! In my case I was using an iPad that I've always used. I've heard that the available memory in the iPad could cause issues, cache needing clearing, etc.
