No luck, I tried uninstalling perian and then added ac3 codec, still no sound. I discovered two folders, one under the hd/library/quicktime < thats where I was dropping the codecs, right now I have the Divx encoder and decoder.
I saw that under HD>System>Library>Quicktime. This folder has a whole bunch of components too.
Yeah, I downloaded vlc-2.0.4 which is recommended for snow leoperd.
It says VLC is not recognized.
