If you have a Wii, and trying to connect it to the HDTV with a HDMI cable, you can use a
component to HDMI video converter switch.
This allows you connect the Wii using a component coverter cable and will convert to HDMI output. The cool thing is this box has 3 additional HDMI inputs that you can switch in, so you can have virtually all of your HD sources connected along with the Wii using HDMI one cable to the HDTV. No more selecting Inputs on the HDTV.
