But it's MUCH less intuitive and harder to setup and get the right aspect
ratio. By specifying crop, then scale, yes you actually are scaling first,
which gets the aspect ratio correct, then you crop the black bars away. This
is intuitive and easy to understand.

But is ogg supported natively in 'Winders'? It probably requires special
tools installed before playing, which means it's too much trouble for
cross-platform.
