They teach what the consumer settings do, and how to set them properly... They don't get into "the color of gray" because (IMHO) then you wouldn't need ISF for anything...;) You will most likely learn something from watching the video, and your TV will most certainly look better when you're done. Some people are convinced that you absolutely HAVE to have the display calibrated by an ISF certified tech. I don't agree. I've seen before and after, and compared to my settings using the DVD, I think I come within 98% without the certification (again IMHO...)

Good luck,
