[MPlayer-users] [BUGREPORT] mencoder segfaults on encoding DVD

[vitko]

Hi everyone, this is strange: mencoder (fresh CVS build) segfaults on encoding 
DVD (actually mirror obtained using

    vobcopy -v -m

). See details below. I'll send gdb backtrace later, as I'll yet have to 
reconfigure and recompile the beast with --enable-debug=3. But maybe someone
will find something useful in the -v output below.
