I try to add a 500mb Mpeg4 video to my iTunes library, however, when I click add file to Library and select the video, iTunes does nothing, it won't show a progress bar at the top, it won't add the video to my library, it won't even give me a message why. I'd love to put this video on my Ipod, can someone help me solve this problem?
My problem was with regard to a particular file, not all files. When I tried to open it with Quicktime, QT, unlike iTunes, gave me an error message that mention bad filename. I was able to shorten the filename and then load it in iTunes.
