I've created my first 5.1 FCPX project and would like to play on an Apple TV2 as well as a Windows 7 HTPC running Windows Media Center.  I've been trolling this and FCPX discussions and still having much difficulty.  I've exported Quicktime movie using ProRes 422, opened in Compressor 4 and verified that file has six channel audio.  I seletect target, HD for Apple Devices, Device Apple TV HD and select include 5.1 sound.
