I believe this produces a playable file

I am not so sure about this one...

So to sum up your report:
"FFmpeg warned me that my output file may be unplayable, but the file does not
play with vlc!"

I assume it works fine with ffplay (for both) and MPlayer (for flac)?

If you want to help, please try to fine the stream specifiers in the sources of
http://xiph.org/quicktime/ (I did not succeed).

You could also try if
ffmpeg -i input.mov -acodec flac outf.wav
play with vlc: If it does, vlc needs to read riff twoccs for tags starting with
"ms" (and it also means many certainly valid files will likely not play), if it
does not play, I would assume vlc does not define twoccs for (vorbis and) flac
(and I would consider it a bad idea if they invent new ones).
