I've got a divx movie I'm trying to play. In WMP the video plays fine but I get no audio.

In the name of the file it lists SBC and 5.1Ch. Under properties it says "Audio format: Unknown". Also under properties below "Other Information" it lists "Nandub v1.0rc2".

Can anyone tell me what audio codec I need to play this thing?

Thanks in advance.

****EDIT***** Sorry, guys. I figured it out. I thought I already had the AC3 codec installed, but it must have got unregistered somehow.
