Interesting.
Maybe it isn't getting the name right that's true.
In linux I get:

libdvdnav: Unable to find map file '/home/ubuntu/.dvdnav/TANGLED.map'

(my wish regarding this in general be to not have this message output
I guess, but now that you mention it, I guess there's some bug in
windows too).

Appears it's trying to do
 fd = open("d:", O_RDONLY); #  177'ish of vm.c

which fails in windows, as you can't open a directory.  Guess it's
more involved than that.

But my original question was, why does it seem to constantly try to
find a .map file, when seemingly it never writes to one?
Thanks!
