Not sure if this helps. Moved onto #0728 (tried #0729 but saw remote CEC issues as others have described) and the problem persists. I have noticed though that if video is sent to the background (by bringing up the TV Guide over the top) then it is fine whilst there. It does go back to exhibiting the issue when it comes back into the foreground though.

I think when running in the background deinterlace defaults to half rate.
Does manually changing the deinterlace method and report if some of the options work better?

Thanks for the reply. So switching the deinterlace method does help. MMAL - Advanced (half) feels like it is blurry - picture feels like there is an echo on the screen as movement occurs. The MMAL - Bob settings feel fine however.
