MENCODER: segfaults caused by v scale

Greetings everybody, I hope someone can help me.

I am trying to re-encode a video I have so that it is readable by the Nokia770. I am using a script that people found works variations of the command line:

mencoder infile.avi -oac mp3lame -ovc lavc -lavcopts vcodec=mpeg4 -vf scale=352:208 -ffourcc DIVX -ofps 15 -o outfile.avi

no matter which variation I use of the command, I always get a Segmentation fault - with no exlanations. Except when I take away the "-vf scale" option: in this case it works perfectly. BUT! For my use it is fundamental to rescale it, since the device is very picky about the frame sizes-bitrates ...

do you have any hint? I didnt find anything on the net concerning segfaults caused by vf scale...

thanks for any help

Alessandro
