I'm not really sure how else to put it, I think you might just be missing it because it's familiar to you. Anyway, it's not that important, but if you look at each pad in the diagram, D is used as the split filters' output pads before that, I was just commenting I didn't know you could connect an output pad, connect it to an input pad and then use the same label again later on. >> For the actual filter though, should it look better on a 60Hz vertical >> refresh panel than 120Hz?

Yes, now I understand that it would reduce the stuttering you can get, I didn't know there were 60Hz display controllers that weren't capable of switching to 48Hz (and 96Hz for 120Hz displays) until recently. But I don't understand why the same 60fps result looks so much worse when the refresh rate is set to 120Hz. Maybe it is because I am trying to view the filtered result in real time instead of writing to disk and playing.
