No Sound?! Help me plz

[optikal]

Hello,
When I load certain files into DivX Player 2.1 I get a error message displaying:


The file contains the following type of data
Audio Data Tag 8192
Telling me to install another audio codec.
I'm not sure which audio codec is needed. Need help plz.

"Audio Data Tag 8192"

This is indicative of an .AC3 codec...
