[packman] dvd authoring consistency

[jdd]

This is for packagers (I gess :-()

https://bugzilla.novell.com/show_bug.cgi?id=684730

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)

thanks
