Codec installation problems

I bought Quicktime Pro to convert avi files so that they are playable on my iPod. I converted it but there was no audio when playing on iPod or iTunes.

Downloaded AC3 and A52 but wasn't able to install them. When I tried 2 install AC3, a text edit file full of junk came up.
With A52, it told me to move two files into a couple folders to start installation, I did and nothing happened. I then tried converting another avi and no sound again.

Try installing Perian instead, its great and mac friendly

Perian - The swiss-army knife of QuickTime components

you still need the audio codec unfortunately Louis even w/ Perian (which i tried previously)

Does the audio play on the mac?

okay I just checked Perian and they include the A52 Codec now.
Installed Perian but can't find where it is to use it!
I clicked on the icon thats on my desktop but thats just to install it again!
Thanks in advance Louis!

You go no where to use Perian. If it's installed it works when needed. You can be sure it's installed by opening System Preferences and look at the very bottom. You should see Perian there and can check it's settings.
