Three possible solutions:
1. Convert the movie (in this case it seems you only need to convert the sound) on your PC to a format/codec-combination that is supported by the TV.
2. Use a device that can play this movie (like your laptop, or maybe some media players) and connect it to your TV via a hdmi-cable or some wireless equivalent.
3. Buy another TV. Be sure to try it with this particular files before you decide.
I have a samsung UE55H6700 smart TV.
I am trying to play some files in m2ts format but i get a message that sound format is not supported becaouse of a missing codec.
Can i do something so i can paly m2ts files??
