I have a Diamond Pro analog camera that is conected by S-video to a Canapus ADVC-110 converter which is connected by firewire to a brand new Mac mini. All I get is a blue screen in iMovie that states camera is connected and playing. I have tried all the suggested resetting/cycling and different sequences of opening software and powering on equipment. Nothing works. The converter worked fine when I connected my VCR with RCA cables to it and firewire to an iBook with iMovie.
