I have a Philips 40PFL7605M/08 firmware 140.40.0.

I have connection problems with my Philips 40PFL7605M/08 and Media Server.
Whenever i play a music or film file, the tv loses connection to the media server after 30-40 minutes.

The media server disappeares from list and doesn't return until I restart the tv.

My media server is a NAS Western Digital MyBookLive - Twonky Media Server 5.1.9

I make a test connecting TV with TVersity Media Server on my notebook.
The connection break after 30-40 minutes also with TVersity Media Server

I don't know how to do!!!
I need help!
