    I'm trying to view a ac3.xvid-fty.avi file and with Quicktime and DivX I did not get audio. I installed the Quicktime ac3 codec for the sound and not only does the audio not work but both times I tried to play the file, the computer crashed. What do I do? Should I use another media player or another plug-in? Please help because I have a lot of avi files I would like to watch.

    If your computer crashed, it probably has other issues. I have the most recent version of every QuickTime codec I can find--including DivX Fusion, 3ivx, Xvid, and AC3--and experience no such problems.

    The Msp
    Try using another player like VLC and see if the problem happens again. VLC has great support for a huge array of file types.

    Can you tell me where didcha get that AC3 codec from? I got mine from and i done as they said, put the codec in the library/quicktime/ folder, but it still plays without sound.

    VLC seems to be able to work with that movie. but im just curious to know if theres anyway to see it using qucktime, coz it looks better on quicktime. :) It's probably just me.

    I have the same AC3 codec as you. I believe that it is the only one. The take away message is that it works. It certainly does not cause problems.

    I am having this same problem Leopard although I don't know if its Leopard specific since I didn't try it on Tiger. I have a file that is in XviD encoded with AC3 audio from what I understand. I installed the AC3 compenent and I still get no audio with video in Quicktime. If I run it in VLC it works fine, but I wanted to play it in frontrow meaning it has to play in quicktime.

    yep the a52 component goes in the audio folder and the ac3 in the QuickTime folder.

    just download Perian and delete the divx and ac3 components as Perian includes these as well as FLV, mkv, avi etc

    I did this download a few weeks back before the Quicktime update. Since the update I have no sound on movies with AC3s again. Anyone know of a fix?

    Been working my *ss off trying to get sound in my AVIs and finally got a solution.

    1. Quit QuickTime
    2. Get Perian at and install it
    3. Delete the old codecs mentioned here (look in Library/QuickTime, System/Library/QuickTime and ~youruser/Library/QuickTime)
    4. Start QuickTime. Tada!
