Not around my mac to try this but did you guys try changing the encoding options? It flashes when in front of VSL too but when you change the encoding options to apple h.263 it worked fine. Not sure if that'll work for M.E. also
Had to post back this works! ADS pyro goes for 130-140 at newegg and you can connect any camera that has svideo or the yellow rca video cable up to the mac and it will work with mix emergency and the mac PiP program.
