Try the latest release (1.2.1) and see if it improves.

Thanks for the help, it works better but still has some problems, it is not always seen by the server serviio tv but this time one time in four works.

What are you running Serviio on - a PC?, which operating system?

The purist may hate this advice but one thing you may want to try (as a work around until fixed) is running another media server on the same PC as Serviio - if using Windows simply enable streaming from Windows Media Server (see http://www.sevenforums.com/tutorials/139310-media-streaming-using-windows-media-player-turn-off.html). Once enabled your Panasonic should show two media servers - one for Windows (WMP, which you can ignore) and one for Serviio. The idea here is that the appearance of the WMP server will hold the Panasonic Media Server screen up long enough for Serviio to be detected (can take a while) and displayed.

Let me know if this helps and if it does, how long roughly it is taking for Serviio to appear.

ps. Serviio's appearance in the Pana Media Server screen shouldn't be effected by what profile you select. Stay with the Panasonic Viera G/GT/DT/UT/VT (2011/2012) profile.

Using windows 7 Ultimate x64bit I enabled windows media player server, I can see perfectly, however serviio still has problems, does not always appear in the panasonic. The profile used is the Panasonic Viera G / GT / DT / UT / VT (2011/2012).
