Is there anyone who can advise/help me with this PLEASE, especially Adobe Staff. I really do need to progress this ASAP.

I recall having similar issues. We changed to name the files .mp4 and have no difficulties. We still use the prefix.

So, if I'm reading this right (i.e. the mp4: stream name prefix appears to cover F4V, MP4, M4A, MOV, MP4V, 3GP, and 3G2 file types), my RTMP requests need to end with mp4:myclip.m4a - is that correct?
That is correct. The folder path if any comes after the mp4: prefix. For some reason now lost to me we coudl not use the m4a extension, and renamed everythign to mp4 (renamed only, no transcode involved) and our paths now look like:
