Why are you surprised? There's two kind of DVD support in MPlayer.

1. libdvdread (aka the new one hacked into mplayer mainly by Arpi afaik)
libdvdread has support to parse IFO files and such, you don't need mount
your DVD either. But libdvdread is for playing a disc imho it's quite useless
to play a single file. libdvdread loads libcss/libdvdcss ON DEMAND so ldd
won't show it ... It's a run time shared library loading mechanism done by
dlopen() and its friends, afaik

2. libcss (aka the old one, hacked into mplayer by me)
This is for playing a SINGLE vob stream with doing disc/title key authentication.
Earlier it was statically linked (I mean libcss) into MPlayer, however it
would have been conflicted with libdvdread so it was your task to decide if
you want old/new support but NOT both of them. However some weeks ago I hacked
libcss support to use dynamic loading as well. So you can compile in (and use)
both of the two DVD support methods, however of course ldd won't show libcss
anymore since it loads libcss on run-time (dlopen/dlsym again).

I hope this brief description would help to realize the truth (well: there's
no spoon, you know) about ldd and DVD support in MPlayer ;-)
