Many thanks for your reply. 
Yes, sorry, what I meant is convert preserving the maximum quality. 
I tried the options you suggested and it worked: 

ffmpeg.exe -i test.mov -vcodec mpeg4 -q:v 2  test.mp4 

What I had tried before that didn't work (I got the "qscale option is ignored" warning) was the exact same command without the -vcodec option 

fmpeg.exe -i test.mov  -q:v 2  test.mp4 

Why does it work with the -vcodec mpeg4 option you suggested, and not without? 

Anyway, many thanks for your help. It does work now.

Since this is nearly impossible, the unavoidable question is: 

Or do you want to ask: 
I want to convert to a WMP-compatible mp4 
file loosing as little quality as possible?

Yes, -vcodec mpeg4 -qscale 2 is a possible solution.

Command line and complete, uncut console output missing.
