    Hi, I have downloaded a film and the playback on VLC is a bit jerky. The picture and sound are great but it just seems a bit jumpy. Looking at the time on the payback it seems to skip a second or so every 3 seconds. So as an example at the start the timer goes: '1s, 3s, 5s, 6s, 8s' etc.

    Just wondering if someone knew whats going on and if they could help me fix the problem :)

    Open the video file in VideoSpec or MediaInfo Mac and attach the report to your next post.
    If not, at least tell us what codec and bitrate is used and how big the file is in MB and how long it is in minutes.
    And what exact Mac with what exact Mac OS X and VLC Player version do you use?

    The culprit, despite the low bitrate, is the RV40 codec, which is a RealVideo codec and you might need the Real Player to play that file, though I've never encountered an .avi file with a Real codec before.

    On a second look, the name says .avi, but the container says RealMedia, thus the file suffix should be .rm.

    Thank you very much! Just downloaded Real Player and it seems to work perfectly well! Never been very good with computers and such, so really appreciate the help :)
