Is there a multiple connector, which I can connect my VCR, DVD and satellite to my television and where can I get it?

Multiple connector? Can you take a picture of what you want to plug it into (the jacks on the back of the devices)?

Sounds like you need a switcher. Usually this would be needed if you only have one input on the TV. Radio Shack is a good place for a basic one which will work, but the quality can suffer. For great quality try Audio Authority. Audio Authority® - Welcome Page
