NAS function TOP, Media Server shock

Conclusion First: The basic NAS functions are top notch: This thing is fast, fast and fast again. No comparison with the crappy D-LINK DNS320. The extremely high-quality appearance is living room ready and the unnecessary by the full-aluminum chassis fan is real only if the thing starts to burn. The Media Server (DLNA) is completely useless. I could cry, because that was a buying criterion!. The box has with functioning DLNA mE the potential to become the reference in this low-price class for years.

BUT: The DLNA service is a joke, is sheer fraud for me and insulted each media server. Why is there the DLNA certification, if it then does not work?!. Have tried everything: The movie streamed (MKV / AVI) will start on TV / laptop, but it increased every 4 seconds for 10 seconds. Say: The function is there, but completely useless. MP3 streaming works fine. As with the Zyxel NAS'en well brauchts only 40 firmware updates until all advertised features running. Not with me.
