upgrading libdvdread from 0.9.3 to 0.9.4 removed /usr/lib/libdvdread.so.2, which stopped mplayer from working (and mplayerplug-in, which is how I noticed the problem). Loading a web page that required mplayer (http://www.apple.com/trailers/) reported the error: "gmplayer: error while loading shared libraries: libdvdread.so.2: "cannot open shared object file: No such file or directory" As a quick fix, I linked libdvdread.so.2 to libdvdread.so.3.0.0
just recompile mplayer
