avi to vob with multiple audio track

[afaa]

Hello,
I would like to convert avi files with multiple audio stream/track to vob or mpeg. This is for the karaoke files. The converted files only have 1 audio stream. Is there a way to do this and keep both audio streams.
Thanks

Found a solution using freeware FFmpeg. Non of the commercial all in one converter software can do multiple audio streams which is sad.

Hello,

Sorry for the delayed reply. Our software could not support multiple audio stream at present, but we could consider to develop it when updating in the future. Thanks & regards，
