hi guys

could anyone help me with setting up a xbox360 on a beovision 6 - 22

i have pluged the red,white and yellow cables into the side of the tv and it does work but the picture quality is very poor. it is much better when i turn the xbox settings to 50hz but then most games only play at 60hz and that is when i lose alot of quality. is the beo6 only 50hz?

anyhelp would be great.
