I don't know how to plug into TV my simple DVD Player, Sony VCR Player and Nintendo Player. To accomplish this on my previous tv,a friend used a Radio Shack 4 way audio-video selector with four buttons to push to use one of the Players listed above. We cannot get use of this equipment through our new Vizio E50001A1 Flat Screen High Definition TV". I am not very "quick" to get electronic things, so please walk me through step by step.
