Best practices export video with 5.1 surround sound

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.

I had the same problem - my findings:

- source has 6 channels --> verified via inspector in Compressor


I create 1 Job (in compressor) with exactly this source:

- one with (a modified) "HD for Appledevices..." giving a *.m4v and "Include 5.1" checked - output is stereo

- one with Quicktime - H.264 + Audio = 5.1 giving a *.mov that does have the 5.1 track


So I consider case #1 as a bug in Compressor 4.02 or the Settings-profile.

Anoying - because I am almost sure it worked in the past!

Hey guys, I've been posting about this in other threads but wanted to provide an update. I emailed Apple's exec team and received two phone calls today, both stating they have received the bug reports and are reviewing the issue. No ETA but at least they are aware of it. I hit the panic button when 10.0.6 rolled out with the same issue.
