Sony Vegas 13 Audio with Multi Stream?

[ssmacc]

Hello,

Does anyone know how to produce a video with multiple Audio Stream? A film with an English, Spanish and a commentary track for example?

I've had a read round and thought I'd cracked it, but I've ended up with multiple audio channels in one stream (at least I think that's what's happened). I'd like to be able to select the different Audio streams in WMP Classic for example...

Any help appreciated...

Couldn't get Vegas to do it. However, I did manage to produce the separate files and remux them using mkvtoolnix.

Cheers,
