i use the good ole home depot lighting rigs, they are cheap and do the job well. Did you happen to white balance your camera the last time you when you got the crap footage? Because int eh end if you white balance your camera right any system will do. i would think about adding some lights so you can light your screen and also light your subject individually. just make sure that wattage is the same on all bulbs so that the light intensity is even. I come from a very budged environment so those are my thoughts for you.
