Audio Stream Not Recognized By Nandub & Virtualdub

[piotr]

Recently I recieved few DivX movies. When trying to edit them with latest Nandub v 1.0r2 or VirtualDub 1.4.7 I got message that audio format is not reconised (tag 0055) and nothing can be done with the movie. File Information says about Audio Stream that Sampling rate is 48000 HZ & Compression unknown.
There are no problems with playing the movies !

Any suggestion how to deal with this ?
