I never had downloaded the software with source code option. Ifhey include ffdshow they would have had to provide you with an offer forhe source of it, but it seems they handle their files with separate filterso it won't help you (and chances are high that they just used one ofhe pre-built ffdshow binaries - this does not free them from havingo offer source and keeping a copy of it themselves, since IMO callinghis non-commercial distribution would be a stretch, but that doesn'teally help you.
