If you are a big Caro Emerald fan, this CD/DVD may be worth getting, but it doesn't compare to the live CD/DVD/blueray set Live in Concert with the Grandmono Orchestra. (Available from her website.) That DVD is excellent, and also includes the concert on CD as well.
Personally, I don't like the 3 remixes. The first two songs on the DVD are probably the best thing on the DVD, but these are from the above DVD anyway. The five songs from the club tour, are fine, but don't compare with the Live in Concert DVD. (It includes backstage footage if that appeals to anyone.) And then it just includes the two music videos for a night like this and back it up. (You can find these on youtube if you want to see what you are getting.)
So I'd advise getting the much cheaper CD of the album, and then the Live Concert 3 disc edition. (Or even just get the concert, as I think the live performances are generally better than the album recordings anyway).
