I went looking for the files to see what changes I could do :), but I take 
it I am not looking for http.c and demux2.c as they do not have the 
stream_t defined anywhere? Mind pointing to some of the files I might 
browse just to get a feeling of what it will take?

I also don't notice mplayer doing any caching to start it's playing... 
Maybe it does it as it begins, but I am wondering is there any chance one 
could modify just the logic of retrieving tracks that would make it more 
serial and not jump/seek all around?

I notice if you save as an mp4 file the timeline slider goes back and 
forth all over the place as if it too has to seek quite a bit.
