Problems with Serviio and Panasonic TV LED 3D TX-L37ET5

Hello!
I happen to have some problems with Serviio and my Panasonic TV LED 3D TX-L37ET5....I tried doing lots of things, nothing works.
1 - My newest problem is, that my TV doesn't find seervio media center, it does pop up on the TV Screen, but when I select it, "connection to server failed".
Yesterday I was watching a movie and this didn't happen. I terminated the server with seervio, relaunched the Internet....nothing seems to work.
2- Yesterday when it worked fine, I was watching a mkv movie, that has 3Gb. After each 8-10 min the movie stopped. The seervio server disappeared. I had to wait for seervio to pop up again on the tv screen, restart the movie and shuffle to the time where I was....this happened like 10 times! (pretty annoying whatching a movie like this....)
i've made a screen shot from the seervio console...Am I doing something wrong?!
thank you in advance...I am so disappointed that this tv can't play "mkv x264. files" from the USB stick... that was my wish with a new TV. I thought seervio could save me with this, but man it's complicated.
