MBL NAS not playing all files on Samsung Smart TV

its a real pain this, tempted to just get a WD media player but i was hoping to reduce the number of things under the TV unit not increase it! plus i have a smasung smart tv upstairs also which i was hoping to play files on via NAS.

will take a look at the guide I think amd give it a go.

this WD MBL is turning into a brick, originally bought for Time Machine back ups, which I had to abondan that plan as it was so chronicallys low it was unusable. It now appears it has problems streaming video.
