I ask because I havent been able to run gem and pd at once without audio pops on screen redraw (and even got pops when I moves the mouse around without gem in complex patches - not dragging anything either!), and I havent been able to get libquicktime and ffmpeg to compile togeather in order to run pdp.
there is a trick with libquicktime and ffmpeg, it would work easily if you'd use libquicktime 0.9.1 ( 0.9.2 brought up all that mess )
cheers, sect
