I should warn you that it is completely useless trying to use most - if not all - video "bridges" to hook up a console to your iMac. The problem with these devices (the ones that take an analog video input and turn it into a digital output for you to plug into Firewire or USB port) is that they have a slight delay. On some the delay is less than half a second, on others the delay can be over two seconds. Whichever the case is, the bridges are great for importing video or TV, but useless for gaming.
