Question

Hi - I recently bought an iMac OS X Leopard. iPhoto works really well with my Sony camera to USB port. However for iMovie I tried linking my Sony DigitalHandycam Model DCR-PC100E to Firewire socket and nothing happens at all. Camcorder works fine in isolation and with different leads works on my old Vaio PC and to television.Can I get a "converter" or do I need to buy a camcorder that appears on Apple website as compatible ?I hope you can help.Regards
