Share Alike (“SA” an arrow going in a circle): You have to license it the same way they did.
No Derivatives (“ND” an equals sign): You may not alter the work.
Non-Commercial: (“NC” A crossed out dollar sign): You can’t earn money from it.
So I guess It’d be ok as long as you follow those guidelines. I wouldn’t do it though.
Also keep in mind that the sales of those DVD’s help fund Blender.
