 Perfect! This works great with 2.1.1 as well as latest zeranoe build. I
 guess I can modify my encoding profiles this way, but I still believe,
 this should be done as default while using -r parameter.

 Thanks a lot anyway! I should dig into a source code and not just rely on
 documentation. I've never heard about this parameter before :-/
