joreg, the problem with the VideoCapture (VideoIn Node) was actually not a Capture Card problem, but a problem with finding the right .fx file later in the graph. I guess the VideoIn Node worked fine as long as you only have one instance of it running. the second instance have curiosities with the analog video input enumeration. since the first boygrouped VideoIn node (not visible on boygroup clients) worked, the problem had to be somewhere else.
Boygroup clients only find .fx files if they are dropped in vvvv’s effect folder. why is that? relative path’s do not seem to work. so for the wishlist: I WANT RELATIVE PATHS SUPPORT FOR BOYGOUPED EFFECTS.
