I'm interested in getting a camcorder to shoot home movies and have been thinking of the Sony HDR-XR105E or HDR-SR11E; both have USB 2.0 connections and something called 'Video Output'. I have an iMac running OSX Leopard and my previous camcorder (which was a tape-based one) connected via the firewire interface. I would prefer to continue doing this as I have used all my USB ports. Does Video Out use the Firewire input? If not, what are some good alternatives to the Sony products that use Firewire instead of USB?
