I just bought a Samsung TV an I want to Know how to connect my direct TV, vcr, and dvd player? I also have a component wire?

If Sat has component(Red, blue, green) use that and red/white(audio) to component input
On TV. Use best connections from VCR to TV. Connect DVD to an Unused Component input.
Is VCR just for playing, Or do you want to record from something(Sat or DVD)?
