DMX/Audio Interference

Hopefully this is the right spot to be posting this - if not, please feel free to move it.

I have been working on a project that is using the ENTTEC DMX USB PRO and ran into a strange interference problem: when certain lights are at full brightness, they begin picking up a pulse that seems to be attached to the music being played.

It probably easier to watch the video, rather than try and describe the problem (this is just a rehearsal video and it's only the first minute or so that goes according to plan - you can see the issue well at 1:20)... Edit: I haven't posted enough to be able to use links yet - if anyone needs to see the video, I can PM a link.

My instinct is that it's a signal crossing issue, but I'm not sure where it's happening - the external hardware/cables etc, or somewhere inside my machine. The data I'm getting in Processing doesn't show the jump in values.

Here is my setup...
Audio: Wii remote --> OSCulator <--> Ableton Live --> Powered Speakers
Lights: Wii remote --> OSCulator --> Processing --> DMX USB Pro --> DMX Dimmer Box --> Lights

I'm also using a MacBook Pro if that makes a difference when it comes to issues drawing power.
