True, and that part works fine, I guess I just misunderstood the whole Mountain Lion thing. Being new to Apple world, I thought my 10.7.5 WAS mountain lion and that I just needed to install a later version.
I would like to stream straight from my Movies folder, rather than moving everything to iTunes. And there's a few things I'd like to mirror from my desktop as well. It works with AirParrot, but would like to know how the resolution in the Mountain Lion mirroring compares to the Airparrot mirroring.
