Oh I suspected that (with the non-blocking IO), after all its logical. 
I wanted to write that it works due to console IO but I wasn't very
"talkative". 
Of course, the call which writes to stdout/stderr doesn't return (if the
output blocks) which keeps the program from running (I'm sure
you know that already). Of course, it works that well because
mencoder is constantly writing to the terminal (every frame).

Correct, but I prefer the C-s method because it has less side-effects
on the execution of scripts, which should also be in the fine manual of
the shell.
