MPlayer for Win32

Hi all,
I'm trying to convert some images to video and I see a segfault when I try
to convert images that aren't on the same directory that mencoder.exe. If I
copy them to the same directory, all works. The command line:

C:\ffmpeg\mencoder>mencoder mf://c:/tmp/*.jpg -mf
w=600:h=800:fps=1:type=jpg -ovc lavc -lavcopts vcodec=mpeg4:mbd=2:trell
-oac copy -o output.avi

And the same with c:\\tmp\\ and also with relative path mf://tmp\\*.jpg

mencoder r29355
