As far as I understand the flags in mplex are mostly so that mplex knows what kind of data to expect. Of course there are incompatible options for some formats and setting the appropriate --format makes mplex ignore those. But the program stream format is still very much a standard thing and not something the mplex developers pulled out of their hats the other day. The reason why quicktime doesn't support it is probably licensing issue of some kind. And of course apple wants everyone to use their magnificent quicktime formats so you can't easily convert into anything usable and change player.
