.B \-panscanrange <-19.0\-99.0> (experimental)
Change the range of the pan-and-scan functionality (default: 1).
Positive values mean multiples of the default range.
Negative numbers mean you can zoom in up to a factor of -panscanrange+1.
E.g. \-panscanrange -3 allows a zoom factor of up to 4.
This feature is experimental.
Do not report bugs unless you are using -vo gl.

.TP
.B \-refreshrate <Hz>
Set the monitor refreshrate in Hz.
Currently only supported by \-vo directx combined with the \-vm option.
