What codec are you editing with and are you using any third-party plugins?

My software:
Pro Maintenance Tools - Tools to keep Final Cut Studio, Final Cut Pro X, Avid Media Composer and Adobe Premiere Pro running smoothly and fix problems when they arise
Pro Media Tools - Edit QuickTime chapters and metadata, detect gamma shifts, edit markers, watch renders and more
More tools...

Did you do the "usual" things like trashing your prefs and repairing the disk permissions?

Does your 2nd monitor run on a different (maybe even slower or less capable) graphics card?
