Hello, Am unable to play the video files on my windows rt surface, but I successfully played them on windows xp and windows 7. I have tried with few third party softwares or player to play them but no success. And one more thing, the default video player is having issues with the files. So please help me what is the solution for my issue. I don't understand what should be done instead of using older pc with windows 7. Please help me with a solution. Thank you.
