Skipping to next file druing playing

Hi all,
first of all I'd like to thank the Serviio team for their great software. Keep it on!
A few days ago I bought a new Samsung TV, model UE40F6400. I updated it with the latest Firmware v1116. Everything works fine with connection with Serviio, i can search the folders. I can play shorter files (less than 40 min) without any trouble, but when I try to play a longer film it plays for a while 5-20 minuts long, than it skips to the nekst file in the folder. If there is no other files in the folder, it stays ther like it has finished playback.
I got it installed on my PC with the following specs:
Win XP x86 SP3 Intel Celeron CPU 1.8 GHz, 2GB RAM
Serviio 1.4 (I tryed 1.2.1, 1.3.1 too)
Selected profile for the TV: Samsung E/F Series
TV and PC are connected through an Ethernet 100/1000 router/switch.
I tryed to install it to another PC with Win 7. The problem is the same. But when I try to send a file from win7 directly from windows to the TV it plays it correctly
I already searched the forum and tried all the tricks that may relate to my problem but nothing worked.
Your help would be really appreciated.
Rgds.
