You should use the code from aspect.c, it supplies functions to store original 
vidres, prescaled size (eg. for svcd where videores is 480x480 but displayres 
is 640x480) and a function to save the screenres, which is the area the 
scaled video should fit into. You can also specify the monitorapsect, if your 
screen is not 4:3, which is the default. A call to the aspect function will 
return the wanted video display size, either only aspect corrected according 
to the monitor-aspect or corrected and zoomed to the maximum area available, 
if the zoom flag is set to 1.
