it's not so simple: those simple minds at BD committee decided to take 
the most idiotic path: carry in the same pid the two streams. The 
demuxer doesn't have a way to choose the right substream because the 
substream ids are not qualified in the PMT, that's why you have to 
use the right command line option.
