A bit off topic but just read this posted elsewhere:
no mention of how to get from a video (in Youtube) back to main youtube menu without exiting portal altogether.
I do wonder why some people buy equipment that is obviously to complex for them, does no one actually pick up a remote and press a few keys to see what happens nowadays? do they have to be led by the hand for everything?
I would it was pretty obvious to try the back button if nothing else.
