Err, sorry, but "does not work" is a bit vague as an error description.

Try something like

No output file created
Mencoder hangs
Mencoder crashes
It takes hours for every frame
Output file not playable
Output file still contains the logo
Output file has the logo replaced by a purple banana
Picture quality is bad
Output file is all black
...

I can see no "error" messages. I just see that the "scale" filter has been
automatically inserted to do colorspace conversion. That's pretty ok.

That's hard to say as long as you don't say what you're doing.

A full command line might be helpful, along with information on how you
created the bitmap you passed to the remove-logo filter.
