I have been using a 3tb external hard disc to store mkv and m4v files for use on my pc with xbmc. However i may be looking to use the drive to connect to my TV. I have a Samsung LE46c 750 and the manual reads as though it can support both files but when i hook up the drive to my Tv the TV detects it but when i select video option it says there nothing there. What am I doing wrong? Any help?
