Is it OK to add bonus CD/DVD releases?

I’ve bought this CD Alex De La Orăștie & Laura, Vol. 5 which contains a bonus DVD (as stated on the front cover).
The DVD is called “De râsu’ lumii, Vol. 2” -
I don’t have the jewel case with the cover art but I got the DVD.
Is it ok to add it as a release?

If yes, then how can I do it? Can I get an example of such a release, containing a bonus CD / DVD?

You should only add full release to MB: CD+DVD.
You can duplicate the CD from another edition and add your DVD, for instance.


Here’s an example of a 3CD+DVD release:
