Please do no buy Composite Cable if you don't want to display in-game to your TV. This allow to output Music, Photo & Video and no in-game and may or may not work with XMB.
You must get the Component Cable if you want to display in-game and XMB to your TV & HDTV.
Tomorrow, I'm gonna return this cable back to Fry's Electronic and get 10 Component cables, hehehe!!!
