Hello,

In order to make some small animations from PNG files created with Pov-Ray,
I have just installed MPlayer/Mencoder on my Linux system. But when I tried
to type the following command line, I get some error messages like  "Error
while decoding frame!" (see output below) and I do know how to solve it, 
therefore, I would really
appreciate if someone could help me.
Thanks a lot,

                    Gilles
