audio, I tried using virtualdubmod which allows you to use one audio from a file with dual audio but it would open the file and I got this error "Birtual block not handled", anyone know how I can convert a MKV file using one of the audios into avi or mpeg2.

I have also tried MKV decompresser which I thought would work BUT I got some error saying unable to render video stream or somin? Its mentioned in the guide about video errors if teh name is changed but I havent changed it. help what can I do.

Thanks
