Recently I went to rip some dvd movies to itunes. When i put the dvd in, dvd player didn't pop up. After a while a box popped up saying something like "You have inserted a disk containing no files os X can read, with options of ignore, or eject. All of my dvd movies do this and they didn't before. My dvds with photos etc on them are read fine. Any ideas what happened? I bought a dvd cleaner thing, but that wouldn't be read either so it wouldn't do its clean. also..i did research this before posting..but none of the problems seemed to be quite like this.
