LOL. This is not overheating. This is either a connection fault or a settings confliction with the 360 and TV.
Overheating causes the console to completely freeze. Or if the overheating affects the GPU, the only graphical thing you see, is textures missing, or textures appearing like pixelated rainbows.
Repeat, whatever Sony fanboy posted this on Youtube doesnt know is how an overheating problem on ANY console looks like.
