I've been downloading Gossip Girl off Limewire and putting them in my iTunes, then transferring them to my iTouch to watch. All of them are mp4, obviously. But today my Season 1-Episode 11 just WON'T be put into iTunes. I've gone to the File>Import File thing (when I do this and click OK the episode isn't there in iTunes) and even tried dragging but when I drag it shows the red no sign (circle with line)...And yes the episode 11 is mp4.. Help me please.
