No, the only sample with multiple video tracks i have is so broken, that
this patch has no visible effect on it.
However it doesn't break anything either, so I guess we might as well do
it by the specs. I'll try to do more tests after I fix asfenc to
properly work with multiple video tracks, so feel free to postpone this
patch if you're feeling overly cautious ;)
