I assume standard definition, single video stream at a time. Yes,
firewire drive should be perfectly happy. Even recording, commflagging
and watching at the same time shouldn't be a problem but I don't know
if I would want to do more than that - especially if you don't have
any other firewire devices that might be drawing bandwidth from the bus.
Your bottleneck will be the processor for the above scenario.
