But spumux *does* embed a palette into the stream....

but the subtitle problem revolves around dvdauthor's non standard use of
the mpg fileformat (using padding sectors to include palette
information).  Stripping that out (by using a fully custom subtitle file
format) would help.

the idea isn't to remove mplex altogether; it's to build some of that
functionality into dvdauthor.  Dvdauthor would still accept multiplexed
streams, but it would just rip them apart and remultiplex it itself
(transparently to the user).
