I am trying to copy movie files from my computer to dvd. I do this using Nero and make a data disc. I even used CopytoDVD and had problems with the same files. I don't convert anything and most of the files work. They play perfectly on the computer. One file plays perfectly and the language is in English if I play on the computer but when I play in my dvd it plays in Spanish and the video is garbled. Thats the issue I'm having. Video is garbled and not clear. Any idea whats causing this? Thanks.
