..which I guess makes it harder for people to fix their bugs.  hmmm.
So maybe add an assert for debug builds, followed by graceful failure
in release?

I think this problem is fairly wide spread and will take awhile to fix
every codec.
OGG's fix isnt great either... 25 fps is PAL.  More common rates are
23.968 or 29.97 fps.
So we'll get a bit uneven implementation.  If a default were done in
util.c it could be consistent.
