OK, so it seems OggExport component was advertising ability to export
from procedures, following the ElectricImage example component by
Apple, and it wasn't actually supporting it, same as the ElectricImage

Unfortunately, after removing the flag advertising the support, the
iMovie doesn't list Ogg as an available option anymore.

It looks like OggExport will need to (at least) support exporting from
procedures properly for it to work with iMovie. Any help implementing
that will be appreciated - right now it doesn't seem like a 15 mins
hack, and there's not much docs or info either.
