I have installed about a half dozen of the 5x1 Monprice switchers with excellent results. I only had one issue with using it with a DirecTV receiver where it wasn't happy.
But, if you intend to hook it up right away and if it doens't work, Monoprice typically is happy to take care of you.
I am actually working tonight and installing one with a Gefen HDMI over RGB adapter and it is working flawlessly.
