I'm new to the Wii world and I have a few questions. First off, does Wii support HD and HDMI cables? If not what hookup do you recommend for best picture and sound? Secondly, are classic controllers wireless or not? Lastly, can someone explain the ultra sensor bar and the clear rubber cases for the wiimotes that plug into the bottom of your wiimotes? Are they worth the extra expense, and do they make the regular clear rubber cases for the wiimotes that dont plug into your wiimote? Thanx for any responses!
