I have a flat screen TV that only has connections in the rear of the unit. I also have my cable box and DVD/VCR combo connected to the TV. I would like to connect my new Wii but the red, yellow and white connections on all 3 pieces are all in use so there is nowhere to connect my Wii cord. I've heard something about an HDMI cable but not quite sure where it goes or how it works. If possible, i'd like to connect my Wii without having to buy extra stuff. In reality, I really just want to hook it up and play. Help a girl out! Thanks!
