I have a Samsung UE40D6100 smart TV and also a Samsung 3D Blu-Ray player. I am trying to play 3d mkv files stored on a NAS box over my lan but it is saying they are an incorrect file format. Yet if I copy the same video file onto a USB flash drive and plug it into the TV or BR player, it plays fine. Anyone know why this is happening, and more importantly how I can get them play over the LAN?

Cheers in advance
