Hi all here is some help to get the AC3 8192 AUDIO DECODER For MAC Systems!!!
I had to download both of these files and copy and paste them into a couple of folders. The A52 component I had to download by itself, as perian didn’t work. I have included the instructions below on how to install these components and links to download them.
I am running Mac OS X Mountain Lion and Quicktime 7 Pro and this work for me (Just remember to read and it should for you too).

How To Play AVI DivX codec Movies on Quicktime in Mac OS X Leopard
(Also Works For Tiger and Above)
Quicktime under Mac OS X Leopard can’t play movie or video files saved in .avi format encoded with DivX format without a little help. Also if you get no sound from AVI files on your Mac, the following AVI audio codec will solve that problem for you.
Here’s what you need to make Quicktime on Mac OS X Leopard (10.5) play .avi movie files.
Click (OR Copy and PASTE) the link into your address bar and Download both of these files:

Quicktime Audio Codec - A52 AVI Audio Codec For Quicktime

Download both of these disk image files (.dmg) and double click them to mount these files (make them visible and accessible through Finder as another Device (top left hand corner of Finder) on your Mac.
Next we need to put these components into the right folders. Within Finder, click on the Xvid Alpha device. Within this Finder window, you should see a file named Xvid_Codec 1.0 alpha.component. You need to copy and paste this item into /Library/QuickTime/ folder on your Mac. The easiest way to find this folder is click on the first device (looks like a metal hard disk) within Finder (mine is called Leopard), then find the folder named Library, and within that, another folder named QuickTime. Paste the Xvid Alpha file into this folder (or drag and drop it if you have two Finder windows open).
For the audio part of playing .avi files in QuickTime you need to place the A52 codec component into /Library/Audio/Plug-ins/Components/ folder. Luckily the author of the A52 audio codec for playing avi files in Mac made shortcuts right within the .dmg file for A52 Codec. When you double click the A52Codec .dmg file you’ll see two huge arrows pointing from the codec files to the folders they should be dropped into so simply drag and drop the two files into the folders (which are actually shortcuts to the correct folders on your Mac machine).
If you want QuickTime to recognize and play Dolby AC3 encoded audio from movies, copy the AC3MovieImport component into the /Library/QuickTime folder as well. This definitely won’t hurt and you’ll probably enjoy it later.
After this if you already have QuickTime running, Quit QuickTime (Command + Q), don’t just Close it, since QuickTime will still be running in the background. You need to fully quit QuickTime and restart it for the codecs to be loaded by QuickTime, so this step is necessary.
After all this try double-clicking your .avi movie file again and see if both audio and video are now being displayed by QuickTime.
Enjoy your movies
The.sit file contains a QuickTime component, which delegates the playback of XviD videos to the DivX codec installed on your system. To install the XviD delegate component on Mac OS X, put the XVIDDelegate.component file in the /Library/QuickTime folder and then reboot. Now you can play your AC3 files on Mac OS X 10.9 Mavericks without loosing sound.

Unable to play videos like MKV and AVI that contains AC3 audio on Mountain Lion? This post tells you an easy way to make AC3 files work on Mac OS X 10.8 Mountain Lion.
User Question: “Hi, there, I recently upgraded to Mac OS X 10.8 Mountain Lion, but it seemed that the upgrade brought me a big trouble. I used Perian as my AC3 Dolby Codec before upgrading to Mountain Lion and it worked well all the time. But now when I try to open some AVI movies with AC3 audio, the sound is gone. This happened since I have installed Mac OS X 10.8. It’s interesting that MOV AC3 and MP4 AC3 can be played just fine on Mac OS X Mountain lion. I’ve learned that Perian is a dead project, which will stop developing updates, so I think this issue will continue, but I also believe there should be a solution to get Mountain Lion playing AC3 sound. Does anyone have any idea on this?”
