Files encoded DV-PAL and played fine in QT. All layers set to mode 10 (play fwd > 0) or 12 (play fwd once > 0). The movies played fine on their own, it was when you had multiple layers at the same time. It sounds as if more RAM won't help, but that sounds counter-intuitive. Surely if the computer is being asked to do more, having more RAM will help?

Editing presets blind...Yes, followed the method you suggest. Try editing a preset blind and edit the intensity attribute. My system moves the fader live on stage, even though the preset I am editing is not loaded and has absolutely nothing to do with what is on stage.

However, updating a preset without destroying the fade times on the intensity attribute is the real time saver for me, if there is a way to do it. What I need to do is update the preset, not really re-snapshot it. Some kind of command similar to a lighting desk that will only update the attributes that have changed and leave everything else alone.

Cheers,
