Poor streaming connection/speed

StephenB... Thanks for the suggestion; the tvix was using SMB, so I changed it to NFS, but I couldn't see any improvement in the file playback. The file is a mkv from a Bluray. Details below;

fastfwd... Sorry about the confusion over my post last night. I posted, then immediately started editing it to get my thoughts into order... you must have replied while I was still editing. Sorry! My thinking (that I 'edited out') was that if the Powerlines were causing a drop of >70% of the NAS speed, then maybe an increase in the NAS speed from the current 25MB/s could lead to a higher speed than the current 6.9 MB/s by the time it's gone through the Powerlines... maybe bringing it up to Bluray capability.

Am I right in thinking I have two issues - 1) the player cannot cope with the throughput needed through its LAN port (although it can via USB2). And 2) even with a player with a capable LAN port, the current drop down to 6.9 MB/s means that the NAS needs to be tweaked (somehow?!) to bring this up? Any other thoughts?
