That's true, but actually I've just thought of a show which actually has 
variable framerates here. It's "Die Sendung mit der Maus", they have video 
footage, 16mm film footage (until a few years they shot everything on film), 
and of course various material shot between 12 and 12000 fps. Currently they 
play everything at 25fps resulting in fixed speedups or slowdowns. With our 
programm they could cleanly just set the factor and even use different 
factors on different scenes.

Ohh OK, BTW, the first kden-file has been created, unfortunately it doesn't 
contain more than the header at the moment.
