Although the VimuPlayer is not the only app of its kind, but makes at first sight a good impression. Many possibilities it also offers. But when streaming video hapert's and that's what should make the app mainly. It may be that it works great with the servers, which are mentioned on the website of the manufacturer. But other UPnP / DLNA server function with other devices also, just this app did not want my UMS (Univeral Media Server) absolutely. Either no picture there, but sound, or both do not or they hang up. The latter is very much dependent on the settings, the default settings do not fit already. But it may also be that the app still needs to be adjusted for the Fire TV stick on which I had run it.
