When trying to convert two divx videos I had with 770encode.pl (default parameters, preset=mplayer), the resulting avi files played a loud, harsh noise instead of the original track. Same results with media converter. I had never this problem when ripping dvd's.

The audio track of those divx videos was in mp3 and I thought the problem could be that it was not rightly decoded and re-encoded, so instead of using wrapper programs I turned directly to mencode, changing the audio encoder from "mp3lame" to "copy". This way, the audio output was correct but the resulting file were almost as large as the original ones.

What kind of command line should I use to get an acceptable audio result while still reducing the file size to around 400 megabytes? Alternatively, what parameters should I pass to 770encode.pl or media converter to avoid that cacophony?

Thanks for your answers :-)
