This is for packagers (I gess :-()
dvd authoring applications are linked on Kde menus some on the multimedia/multimedia burning (gravure multimedia) some on multimedia/multimedia editing (modification multimedia).
mostly, I guess, because most can write dvd on the fly.
It's not very important, but we should choose one of these place and put all of them in the same one or use both (set two links)
