Nick, I was able to record my first video set. The sound, the video, the effects, and transitions were all captured perfectly. I used the M-Audio USB Audiophile Interface. My mixer has a coaxial digital output, from the mixer (with a digital coaxial cable) into the interface (s/pdif input port) then from the interface (USB output port) into the MacBook Pro (USB input port.) Thanks for your help. Eduardo Serrano
