Hello to everyone, I've recently bought a Samsung EU40JU6400 (softwareT-HKMDEUC-1214.0) and I am having many troubles having it play mkv files. My mkv and avi files are usually on a samsung 2tb drive (ntfs formatted): connecting it to the TV I can basically play every .avi files but some .mkv files result in "unexpected error occurred". (the files are ealthy and playable) If I connect my hard drive to my router (fritz.box 3490 with DLNA server) the same "bad" mkv become playable. Except that now every .mkv file is not seekable, I cannot pause,rewind or fast forward. But it gets weirder: if I share the very same files using my pc/mac I can play everything without any problem. But it is really an over-complication: having the drive attached to the router, shared to a pc that runs kodi which in turn shares it with the tv using DLNA.. I'm having headache just thinking about it. Is anybody else having problems playing mkv files on this TV? I'm seriously considering returning it and looking for a more compatible model.. Thank you to every one who is willing to help!
