I'm using a Canon GL2 to record movies. Hooking up to the desktop system via firewire 400, using front and back ports, the video quality is horrible and blocky with lots of a/v artifacting. So much so that the video looks like I'm trying to stream over a dial up connection. Hooking the camera up to my laptop, using same firewire cable, the quality is as it should be. Both systems are using iMovie 08 and running Leopard. Things I've done other than trying a different computer and firewire ports: *at first I thought that maybe the firewire port has dust or something that was making the contact bad, cleaned out the port with compressed air, no change in quality *lowered recording quality on the cam *changed to a different tape for recording *don't have a different firewire cable for testing as the wife is out of town with her cam and has it, but I don't think the cable is an issue since the quality is good on the lappy *I have an appointment with the folks a the genius br this afternoon to talk things over, but I'm doubting they will be much help Another thought that I just had; is it possible to overlaod the firewire bus or data channel that the incoming stream would be riding on? I have two external drives connected via my cinema display. Would that have any bearing on the import quality? Any help would be fantastic, thanks.
