Mediabrowser and Samsung TV F6200

Hello,
On the same local network (100Mbps) with TV Samsung UE40F6200, Serviio works perfectly but with access mediabrowser, I can not play a movie (AVI, MP4). Access is very very slow.
I connect directly to my local server with 100Mbps: http://192.168.1.105:23424/mediabrowser.
From the server, locally, mediabrowser works perfectly.
Internet access from the TV yet allows me to play movies in HD by connecting me from the internet.
I run Serviio-Pro V1.5.2
Can you help me to operate MediaBrowser ?
Thank you for your answer
