Thanks for your response. When you say "Image Speed" parameter, what are you referring to? Is that Image Smoothness? I've tried playing with that parameter and if I set my x position to a snap, that parameter does nothing. The x-position still snaps. Even if I don't set it to a snap, it doesn't appear to do anything to the x movement smoothness.

Part of the problem with scrolling a PSD is that if I move the x position one Catalyst step at a time (not DMX, just standalone) that every few steps the letters appear to be in the gap between pixels. So whenever you go through that step when scrolling the x position, the whole word appears to go dim every few steps and you get a nice, undesirable pulsing of brightness as the word falls through the gaps in the pixels.

I also tried using Unity Scale, but that doesn't really help. Same problems as before. Maybe it is just not possible when all I have to play with is 6x72 pixels.
