I second the idea of not mounting it on the fireplace. I visited someone that had one mounted like this and I never want to go back there again.

If you don't have a stand for the VP180 to mount under the tv, then I would revert back to a VP150. I'm using an in/on wall VP150 with good results. I would use the On wall version, if I couldn't mount it in the wall, like I have it.
