Hey Nick, I seem to be having the same problem when an audio file and the automatic visual file loads but only then. If I have two video files loaded, everything runs smoothly. But as soon as an audio file and visual get loaded, it makes the display screen, my monitor, and serato waveforms stutter/glitch. Please help?!?!
