Mine apparently doesn't crash in a manner to provide a backtrace, but 
absolutely nothing plays with dvdnav:// because of r1245 with "Assertion 
failed: 0, file libdvdnav/vm/vm.c, line 1586" and not just my build:

- MPlayer crashed. This shouldn't happen.
   It can be a bug in the MPlayer code _or_ in your drivers _or_ in your
   gcc version. If you think it's MPlayer's fault, please read
   DOCS/HTML/en/bugreports.html and follow the instructions there. We 
can't and
   won't help unless you provide this information when reporting a 
possible bug.
