Hi all, I have tried both FlaskMPEG and xmpeg and with both programs, I don't have the mp3 codec listed. Both the guides and FAQs say to use mp3 instead of DivX audio when encoding to DivX. I tried what the FAQ said with respect to reinstalling the DivX codec, (both version 4 and 5, one at a time), and no luck. The FAQ also mentions a program to run called register_divx.exe, but I can't find that. Can anyone make any suggestions for me to get my mp3 codec back??? Thanks, Mike

You could install the LAME ACM codec.

DIVX 3 CODEC 

The divx3 codec is the one that reinstalls the mp3 codecs. Reinstalling that should work. Restart then try again.
