I get to the point where Windows 7 has loaded the initial files and a blue screen (sort of an underwater view looking up at the sun.. if you follow) with the Windows 7 Build 7000 in the bottom right hand corner. The mouse starts to work and the mouse cursor changes to a circle and spins a couple of times, but then stops and changes back to the standard mouse arrow. The DVD drive never spins up during that time. I've created the DVD twice (once at high speed and another at low speed) with no luck. Any idea?
