He hacked some code of xine to work in mplayer. I think it has some
redundant and unused parts too, like descrambling.
The .ifo stuff should be rewritten from scratch. mplayer internals
differ a LOT from xine! and this way we avoid licensing problems too.

I think that .ifo file can't be so hard to parse. that DVD players uses
simple cheap processors with limited instruction set and low clock freq.
