I don't know much about the intricate details of H.264, but:

If you think this could be the cause, you could add "-x264opts ref=1".
But x264 should be getting its profiles and levels right by itself.

As you mention, that doesn't seem to be an issue, but I think that can
be manipulated with "-tag:a lpcm".

You can dump the x264 encoding parameters using
$ strings < file.mov | grep x264
You might also want to show us your conversion command line (which you
did) and its complete, uncut console output (but I think that won't
help much here).
