I'm only using .mp4 formats and I'm shooting for 700 MB. I downloaded a second movie to see if it was something with the previous movie itself and the same thing happened.

I import it or drag it into iTunes and iTunes goes through all of the motions of importing but nothing happens. I set iTunes to be the standard viewer and shut it down, then double clicked on the movie in the library and it started up but nothing happened. I tried to import from the file menu in iTunes, it found the movie and indicated I could import it, but when I hit Open, nothing happened.

What could be wrong?

Note: Music still works fine
