It's apparently not quite that simple in the US, since Tom Paris got a new name in Voyager so they didn't have to pay Royalties in every episode for Nick Lacarno
I think the difference is in the US you get paid if they use your character but you don't get any say over what they do with it.
Ahhhh...OK, yea, havng to pay for a character's usage, is often enough of a deterrent in itself.
