[MPlayer-users] Mplayer crashes while playing DVD

[JonY]

Hi,

I am using MPlayer dev-SVN-r24302-4.2.1 on Windows MingW. When I pressed 
the "@" button to skip to the next chapter of the DVD, Mplayer crashed.

Unfortunately I do not know how to use GDB, maybe somebody can at least 
tell me what went wrong. Is it caused by a bad DVD?

(gdb) r

(gdb) q

It didn't crash when I played title 1 or if I used the PageUp button to 
skip ahead. What should I do next?
