I'm wondering if wav stems out of ProTools would be more reliable for these interleaved tracks because in googling I read that with AAFs the audio media is still mono tracks joined by metadata. Does a wav polyphonic track have separate tracks under the hood that are joined by metadata or are they a homogenized track muxing the audio media?
All my past experience has been that the networks I've delivered to didn't want interleaved tracks which I think had something to do with how their media servers worked.
Here is a screen grab of ProTools export box:

I'm getting confused.Your original specs refer to SMPTE ST 377-4:2012. This is about MXF.Now, for remapping Wave files from mono to poly / channel mapping, I'm currently working on that.(And more, it can also correct / measure loudness, correct stems, omit Theatrical etc.)(web page needs an update, but the demo is the latest (for now, I'll make updates all the time.)

I asked the protools mixer to give me an aaf with interleaved stereo and 5.1 tracks but when I import them they come in all mono tracks. Also he said that ProTools can not make an interleaved 5.1 track to smpte order of (L,R,C,Lfe,Ls,Rs). What's up with this? I googled and found that the media essence stays mono but metadata joins the tracks. Ultimately the delivery want 5 Stereo track (1-5) and one 5.1 track (6). I figured if the aaf came in that way it would go out that way. My other option is to audio mixdown to interleaved tracks. Perhaps I should just chuck out the whole aaf and just go for wav files as I assume they are immune to the Avid confusing, and perhaps proprietary, multichannel track metadata.

I don't really have an answer for you, but does the spec require a QuickTime file? Or is MXF a possibility?

I'm use to delivering mono stems that I label using the preset names available in QT 7 for (L,R,C,Lfe,Ls,Rs) Lt,Rt. But this delivery spec wants stereo and 5.1 tracks. I suppose I could turn the tracks into stereo and 5.1 in Avid before exporting a QT Ref or maybe even a same as source. What I'm not sure of is the labeling requriements mentioned. Where do you add the labels? I guess I've been doing it in QT 7 as mentioned above but that only has certain name choices.
