    Choppy video playback using iTunes/QuickTime on MP4/H.264 videos

    I downloaded some iTunesU videos from Stanford using iTunes to download. The videos are MP4/H.264 and I thought that since I used iTunes to download them they would playback properly but they are unwatchable. However, VLC Media Player has no problem playing them. I am running WINXP/SP3 with all latest updates. Is something wrong with my iTunes?

    Yup, it has an improper codec or a corrupt codec most likely since VLC carries its own codec for playback and they work so you know its not the computer or the files. The only thing that seems to be an effective fix is to completely uninstall iTunes and any Apple-related software like Quicktime if also installed, and then reinstall the latest version after a restart or two.

    Or just use VLC Player. If it works, this is the simplest solution. But if iTunes and QuickTime are not recently updated, now is the time to get them up to date. This is a security issue, more than a playback issue.

    Vlc

    Thanks, that's what I decided to do anyway. Better quality video and necessary codecs.

    Cool

    Don't forget to update the iTunes and QuickTime programs as Bob says it is a security issue that is very needed especially for QuickTime.
