My tv is Samsung ue48h6670 - which is a 2014 model and seems to support pretty much all file types. As a tv it is unique to the UK, but is the equivalent of the ue48h6700. Iâ€™m using Plex for Samsung to stream from Mac (OS X Yosemite) to the TV. The Plex for Samsung is about the only plex client that will support most file formats - including m2ts, mkv etc. Iâ€™ve managed to backup my Blu-ray film by using a trial version of ByteCopy and then remuxed it to m2ts which plays perfectly.
