Good point, but this raises the whole ugly question of the least crappy
way of setting a default for only one format in the monster that is
movenc.c, and if that's even a good idea. It's non-obvious behavior to
have different movflag defaults for different "formats", IMO.

Actually, I'm wondering why we allow it to be written for other formats
at all in the first place?

It looks like those are quoted from the JPEG XR sequence spec? Confusing.

I have CC'd Yusuke on this email, as he may be able to provide insight.
