It sounds like the problem if SDL_mixer - if it expects (and provides NO other 
alternative) a single buffer for the entire stream, then either it's just 
badly designed, or it's a poor fit for what you're trying to do. The other 
possibility is that there _is_ some other way to get data into SDL_mixer - if 
there is, then you should probably be using that. 

The problem isn't libvorbisfile or your pack-file-scheme (this works fine: as 
I said, you can make this work perfectly if you treat it as a true 
seekable-file - and from what you said it is). 

You're not being an idiot (and I didn't mean to imply that you were, just to 
suggest that there ARE better approaches), I'm just suggesting some ways to 
make your application work better. 

Not being familiar with SDL_mixer, I can't suggest what exactly you should be 
doing with it to make this work more sensibly, sorry.

Mike
