This is NOT working with my external Isight firewire camera. No matter what I do, it always turns on the internal Isight, which has far worse framerate. I was able to get it to work a few times the first time I tried, by opening Ichat preferences and having the internal isight already on before trying in ME. Anyone know how to completly disable the internal Isight with disabling DV video functionality, therefore allow the external isight to always come on. Thanks this would help a great deal.
