I was looking for something to plug into the AV system so that I could feed the BluRay, a future satellite receiver and output from an iPad through the HDMI connection.
Found this item on Amazon and works like a charm. Switches to whichever source is active automatically. Slid out the BluRay, hooked it up and a couple of additional HDMI cables and was off and running.
