I have the TV model 50inch TU8000, and although it will recognise every usb thumb stick or hdd, it won't let me play any of the files, saying they're incompatible. So I downloaded a file converter to change to h.264 codec and they still won't play. It will play however on my Samsung bluray player. Ive tried every file format and nothing! Mp3s, mp4s, mkv and more and also different sizes of hdd. Samsung just reply with a list of available codecs and formats, and as far as I can tell, they're correct. Help?!
