What i find really weird is that i just got my pc burner etc couple weeks ago and i made an iso image of troy and burned on to a 50 gb disc for my personal back up with no problems but due to the write speed being too high it kept freezing when playing it on my dvd player so i desided to lower speed 4x and make another to no avail so far have not been able to create an image will keep trying and post back if problem solved
