I'm not argueing. I'm quoting an ffmpeg trac ticket where someone
discovered that dvdauthor appears to suffer from this, and it had been
linked to the same observation of "apparent" stream order. I am
postulating a guess that this may be why the OP's tools have this
issue. I neither tried nor investigated AviDemux and MkvMerge, although
we could dive into their code if we wanted to. (I don't. ;-))

Yes, I know that it can change at any time. I wonder if those tools do
know. They might have a totally different issue, related or not related
to what ffmpeg is creating.
