There are Active Firewire booster cables just as you have active USB cables. Dunno how good they are ,as im on a 40D and using active usb cables but for the 40D they work wonders and im right now using 12 meters worth of usb cable (2 active 5m and a normal 2 m for the last stretch) which is all i need in my studio.
