Divx audio on Win2000

[Topher5000]

I recently upgraded from win98se to win2000, because Musicmatch Jukebox 7.5 was stuttering when playing mp3's. I think I messed up installing too many codecs. I had no problems using tmpgenc to convert avi's to mpgs before, but now tmpgenc doesn't recognize the audio portion. When I open it in virtualdub & get the file info, it says that the sampling rate is 44100khz, 2 channels, 0-bit sample precision & that the compression is unknown. This happens with files I've converted before. The avi's play in Win Media Player, though.
I don't want to go overboard with the codecs again.
Can anybody tell me which codec I need?

Thanks,

Chris

Open the file in gSpot!
It will tell you what codec you need and if it is installed
