modules have changed as of the new kernel apparently so vloopback is dead once you move away from the 2.4 kernel range.

at least thats how im reading/experienceing with trying to compile it:

any idea how to run this through effectv now? This isnt the right thing for us is it now? we still need to feed it out through a 2nd video deviece if im reading properly on how to use vloopback. 

Any plans to move this forwards to work with some sort of output in the 2.6 kernel?
