A few days ago I wanted to play Lord of the Rings Return of the King on my Xbox. Unfortunately the game won't boot.

I have PAL Xbox and the PAL version of Return of the King. However my Xbox runs in NTSC mode because I'm using a YUV cable.

I switched the Xbox back to PAL mode. The game is working with this setting, however I cannot use 480p or 720p resolutions in PAL mode.

Is it possible to get the game working in NTSC mode?
