Samsung tv streaming video problem from MBL

Hi just bought my MBL last month and when i play video direct from my hard using my tv the video stops every 3 to 4 minute and says loading or preparing to play.

If i use my mobile phone ( through the my cloud app) i can beam it straight to the tv and no issues with stopping. Also same file from my computer through a program called samsung pc share manager same no problems.

Only when i use the media player on my TV straight from my MBL.

Media streaming is enabled, port forwarding is also done.

Which media server is on your MBL?  Twonky or DLNA?   You can check via the Media page of the setup screen.
