We need to connect a wii and a dvd player up to our 32 in Emerson? Unsure of which jacks to use?

First, you must figure out If your TV has component video inputs. This is a set of five cables (red, blue and green for video and red and white for audio) and will give you the best picture on an hdtv

Then, If your TV does not have the component video cables, you will be using the red white and yellow composite yellows the system came with. A very simple connection.

Last, If your TV does have the component video inputs, you will need to buy a set of the Nintendo Wii Component Video cables from Walmart, Target or any other gaming store. These will enable widescreen view and the best picture quality.

To connect your DVD player, you need to located the composite video inputs and s-video. Composite video is a yellow, female RCA jack, normally found next to two audio jacks, one red, the other white. The three jacks together provide an interface for audiovisual connections. The red RCA jack connects the right channel of a stereo system, while the white RCA jack connects the left. The yellow composite video jack rounds out the set.

When playing the Wii, you will need to be on the correct video input "Component"

When playing the DVD, you will be on "Composite/Svideo."

The Wii system used the HDMI cable.The DVD player used RCA component video cables YRW.This configuration work best,than no conflict berween HDMI ports.U can get both of these cables in websites like Amazon.com,Ebay.com to buy.
