OK, this what I have found out. the disco ball is out of the picture right now beause Blender doe no have the capability to throw light around. I will add that later.
I am still having issues with with the disco lights. I am able to choose the material (video) i want to use, but still am not getting the result I am looking for. So this is what I am going to try. I am going to make a path and attach a plane with the video on it. the question is, how to I link the path and plane. after that how do I set it sos the plane goes forward and when it gets to the end of the path, it reverses back.
