My ‘workaround’ was to give up on capturing through firewire. Instead, I used S-Video through a BlackMagic Intensity Pro to DV; yes, I’m very cheap and a noob. The results were decent and got the job done. I’m still unsatisfied; but, my mentor in this business keeps trying to beat into my skull that one can’t let the perfect be the enemy of the good. I do try to learn.
