I assume that the difference in the two istances are due to different vo.
Usually the first instance uses xv and the second x11 because xv is already
used (check the output).
If this is the case then using -vo x11 will make mplayer work for
the first instance too. But this is only a workaround. Really you
should find a way to use -vo xv (may be with -norct as suggested in
the other post).
