Try the attached patch. I put it together when messing around with
Otvos Atilla's dvdnav patch. The assert() will always fail if the $HOME
environment variable is not set, which afaik doesn't get set by default
in Windows XP. I modified it to check for HOME, HOMEPATH, and
USERPROFILE, the latter 2 being the most common in XP.

The vm.c changes are to properly read the dvd titles using dvdread
functions. Borrowed from a VLC contrib patch...

When I compiled dvdnav in mingw, I first installed libdvdcss with
--disable-shared --enable-static. I then had to configure libdvdnav and
manually add the HAVE_CSS_H or something similar in config.h and added
-ldvdcss to the Makefile in order to have dvdnav statically link
against it (again with --disable-shared --enable-static).

Regards,
Erik
