There should be (and are) two logical video streams - I'm trying to create 
a file with a "main" video, "alternate" video and a few different 
soundtracks.

I'm trying to merge though, not concatinate!

If there is one file containing video #1 followed by video #2, I could see 
it wanting multiple skeletons. I may have mis-read the specs, but for one 
video with main video + alternate angle video + english audio + french 
audio, I would've thought that should be one skeleton with a fisbone per 
track, with the fisbone's describing the relations between the tracks?

Thanks
