I am not a tech savy guy but it seems like the most peculiar thing just happened... I recieved a dvd from a friend, I don't know much about his drive or format except that he is running a single layer burner. My dvd player will read a word file from the dvd but it won't recognize an application file on the exact same dvd. I know the file is on the dvd, or at least the space is taken up. Any ideas?
