In VLC log is empty, so i'm not sure how i can provite a log file (i'm
more a php guy then a software developer)
I know how to handle patches (with php files and some cpp scripts) but
building libdvdnav will be new for me...
I found the last libdvdnav-4.1.3.tar.bz2 file on the server, i will
try to find out how to build it to a .dll

The file is really small so i thought if you open it you will get the
crash directly and can see in debug what's going on, but perhaps i\m
wrong... looking in the log seems more complicated then just running
in debug and see the error. (also not sure if this is possible with
dll files)

Offtopic: is there some change log of the versions: 4.1.1 to 4.1.2 to
4.1.3 etc.? I understand VLC now uses 4.1.1, so i was just interested
in the new changes.
