Blu-ray with small disappointments

I want about the band and their music now do not write, I think every fan knows what makes the music of Nightwish so unique. So I myself (as certainly many others) just got a new Blu-ray release of Nightwish. But I am annoyed about two things, one thing is serious: The sound comes in DTS very dull and undifferentiated in the ears, Floors voice is reasonably clear only in stereo.
The second annoyance is that there is no German subtitles in the long documentation. While I can reasonably English, but the insertions occur in such rapid changes that it would be extremely helpful to read them in German. In such a box set that was supposed to be in there. So I can not say that I would be completely satisfied.
