Best I can tell, anytime I play any of my 720p movies, the TV's mode will change to 50hz. If I go into the xbox settings and disable 50hz mode, the videos will successfully change the display mode and play in 24hz. The problem with doing this is that all of my PAL tv content will then be displayed using 60hz which causes judder.
1080p movies seem to correctly change to display mode to 24hz even with the 50hz option enabled in the xbox's settings.
Any thoughts? Before the display mode switching feature was introduced I never payed much attention to this but now I'd like to make sure it's working as intended. Anyone else notice this?
