Would be nice sometimes ;)

I will try this. Indeed I used pdp before and i'm on an osx-platform; 
that's why i was thinking of connecting a metro. So if I understand it 
correctly, you cannot change the speed of the different individual 
video-sources [when using separator 4 example] but only the render-speed 
of Gemwin, which means all the individual sources are affected. Is there 
then a way to 'delay' one source from the other when using separator?

I have to compare some capturing-software to see if it is actually 
faster then pd/Gem. Will tell you the results if they are remarkable enough.


Thanks,
Sara
