[theora] multiple audio streams

[Patrick Byrne]

I need to make an ogg-theora file with multiple audio streams.

ffmpeg2theora-0.18.exe does not appear to support these.

I set up a graph with 2 audio streams in graphedit, but only the theora 
stream and 1 audio stream appear in the resulting ogg file.

Can someone please advise? Is there some way I can make these or some 
other tools do what I want, or am I going to have to write my own encoder?

Thanks
