Is the dvd you were lent legal. If so, what file format was the original disk (if you are confused, download gspot (google it), and check out the original dvd. it sounds like either personal or pirated video (pirated video is not allowed here). People are too quick to jump at the ilegal thing though, so tell us what you got.
You basically need to convert to a standard dvd and nerop should do it (if you do it right). So what file format is the disk you were given (will it pl;ay on a dvd player, ans if not, what does gspot say about it).??
