[Question] Converting Ogg divx movie file into mp3 audio codec

[momentum]

I have got a divx movie which can be displyed with ordinary MP6.4, but encoded in ogg audio codec. what I want to do is to convert this file into divx5.5 with mp3 audio codec to get rid of OGG audio codec.
I tried nandubmod and several other appls in vain. When I tried it with NandubMod, it produces divx movie file without sound.
Can you tell me what appls should I use for this purpose?

Thanks in advance

Converting divx to DIVX5 you'll loose quality. Converting ogg vorbis to MP3 you'll loose again quality.

I dont mind of sound quality. Just let me know how to do it

Let me, before teaching me, specify what I want to do.

1. Cut part of OGM movie file without loosing sound. I dont mind whatever the audio format will be as far as I can hear the sound.
2. Join the file with the other dix movie file
3. Even if step 2 is not possible, I still prefer to have the shorten file.


Thanks
