UE40D5500 dlna issue

[capthookb]

Hello to all. I was wondering if someone can help me out
I was running on my laptop a dlna server (minidlna on archlinux) in the past without problems.
The other day i thought i would try to run samygo.
I followed this procedure: http://wiki.samygo.tv/index.php5/Root_a ... cpu_models and installed samygo widgets. I ran it without problems but sometime i got a message telling me that smarthub needs to be updated. I guess it deleted samygo widget because i couldn't find it anymore. I might have altered a few settings in service menu as well but i can't remember what. TV seems to work fine accept of an issue of disconnection i'm having with minidlna. I fire up minidlna and open the tv. The TV discovers minidlna and i can browse the media fine. I select a movie to watch, and then after a few minutes, or one minute i get a message that dlna server was disconnected, and TV returns to Tuner. The minidlna hasn't terminated, i can ping tv from my laptop and vice versa, so it's not a disconnection (wire, ip or anything like that).
If i restart minidlna, the TV won't discover it. It will discover it if i turn off the TV and then turn it back on or, if i go to network settings and test my settings. After the test, the minidlna server will popup..

Does anyone has any idea of what could be wrong?
