Fast Picture / No Sound

On certain divx videos that I have downloaded, the video portion plays too fast with no audio. I have searched hi and low for the correct codec, but I can’t seem to find it. I have downloaded the AC3 and others, but the problem still presists.

Any suggestions would be greatly welcomed.

Use gspot and let it tell you what codecs you need for the movie. But i would just uninstall all your codecs and download the ACE Mega Codecs pack and it has all the codecs you will need for sometime to come.
