    Don't forget that the .avi file is just a simple container in which the sound and audio files are kept. Just because it's an .avi file doesn't mean that QuickTime will play it as the audio or video may have been encoded using a codec that is unfamiliar to QuickTime.

    I had a look around and found this:

    Learn why an .AVI file may not play as expected in QuickTime Player.

    AVI stands for Audio Video Interleave. The .AVI format is what is known as a container format. It specifies a way in which a file may contain audio and video data. It does not specify how that data is encoded. The encoding of audio and video data is specified in what are known as codecs. A codec (short for COmpressor/DECompressor) tells the computer how to decode the audio and video tracks that have been encoded within the .AVI file. QuickTime Player can use numerous codecs by default. You can also add additional codecs to extend QuickTime's features using plug-ins or third-party installations.

    When QuickTime opens an .AVI file, it checks to see which codecs were used to encode the audio and video tracks within it. For example, an .AVI file may contain a video track encoded in the Cinepak codec and an audio track encoded with the ALaw 2:1 codec. If both the audio and the video were compressed using a codec that QuickTime can use, the file will play normally. If the audio or video or both were created using codecs that QuickTime cannot use, you may see a message like the following:

    "QuickTime is missing the software needed to perform this operation. Unfortunately, it is not available on the QuickTime server"

    or
    "You may experience problems playing a video track in "filename.avi" because the required compressor could not be found."
    These messages are not an indication that anything is wrong with QuickTime Player.
    These codecs below are also useful and fill more specific need rather than act as a swiss army knife like Perian.

    3ivX codec. A free version of this MPEG4 codec is available for Mac users on their download page.
    A52 codec. This codec is very useful for viewing .avi files encoded with A52 audio.
    AC3 codec. This codec is very useful for viewing .avi files encoded with AC3 audio.
    DivX for Mac codec. A free version is available for watching DivX movies, a commercial solution for encoding movies is available as a free 15 day demo. Free beta versions (including DivX 6 for Intel based macs) are also available from labs.divx.com
    Flip4Mac. A free solution, offering playback of AVI, ASF, ASX and non-DRM protected WMA and WMV files.

    Just open the .dmg and double-click the codec to install.

    wow! no i didnt.. mine looks nothing like that..


    when i downloaded "ac3movieimport" file from the link u gave me..it just put itself on my desktop as a "component" file with a white box..

    when i downloaded "a52codec" file from the link u gave me...it put a folder titled "a52codec" on my desktop...when i click on it , it has the "a52codec.component" icon of a white box along with "apple license.txt" "read me.txt" and other misc. files..


    im confused did udownload something different because ur window is labeled "a52codec 1.7.2" and mine is just titled "A52codec" ...

    yours also has the ac3movieimport.component icon within that folder..did u manually do that or it just downloaded like that?

    I didn't realise that I have the Universal version for my Intel Core2Duo iMac.

    I got it from here:


    Finally we have a working AC3 codec that works on the Intel Macs. Get it from A52Codec 1.7.2 - VersionTracker. This one really works

    Usually you will find AC3 audio on those common DivX movies, DVDs etc. Until now ac3 audio would not play on the Intel Macs- both on Front Row or Quick Time. Sometime back, somewhere on the web, I came across another universal ac3 code for QT, but this one just kept crashing the QA player or Front Row.

    With this new A52Codec v 1.7.2 universal binary available at Version Tracker, ac3 audio playes great on QT or Front row. The code appears pretty stable and the audio clear.

    The download comes in a dmg format. After clicking on the DMG from the Finder, it’s almost drag and drop install.

    Drag & drop the A52Codec.component into /Library/Audio/Plug-Ins/Components
    Drag & drop the AC3MovieImport.compontent into /Library/QuickTime
    Drag & drop A52Preferences.app to your Applications folder.

    OK let's backtrack a little, have you ever been able to play avi or mpeg videos and have audio/video without any hassle?

    What are your mac specs?
