As far as I know (ok, it's only my own experience with 2 different lite-ons and nero 5.5 oem bundled ) you should have had a nero oem cd with your drive.
On this cd there is an installer for 'nero media player' (as well as nero itself and InCD) and integrated to your installed nero oem there should be the label editor as well as (as far as I can remember) 4 preconfigured labels.
So, buying the boxed version is only a matter of physical contact.
All plugins (mpeg2svcd, mp3, mp3pro etc.) have to be bought (and downloaded) seperately and are (correct me if I'm wrong) not included with the boxed version or any other.
Ah yeah, you can of course update your oem version with exising nero updates (188.8.131.52 should be newest)
Understanding is a three-edged sword:
our side, their side and the truth.
