OK, this suggests to me that ffmpeg that is causing (at least part of)
the problem, not (just) get_iplayer or AtomicParsley

So, currently in my version of get_iplayer:

1 rtmpdump downloads flv
2 ffmpeg remuxes flv to aac
3 ffmpeg remuxes aac to m4a and removes ADTS
4 atomicparsley tags the m4a

Your testing shows that ffmpeg at least is causing a problem with it's
m4a handling and that EasyTag corrects this but AtomicParsley does not

Does EasyTag have command line options that we can test?
