Sorry, let me try to explain a little better.
In the XDCAM files, the audio channels are all discrete. All 8 channels are separate and show up as in my original post when viewed with quicktime.
In compressor, I can chose many options including stereo but I don’t see any options that yield the same discrete channel output. There are options for 8.0, and Octagonal but the resulting audio format shows up in quicktime as just that: 8.0 or Octagonal as opposed to the 8 discrete channels we are looking for.
