I've got the DIGITAL VIDEO ESSENTIALS, and although I have yet to go through the whole Disc, it works well also. First, I discovered my upscaling DVD player doesn't do "black" levels well at all, so I been kinda skrood from the start. Is black level important to you? I've found tuning disks attempt to set dark too low to see some of the detail still in the picture. Maybe that's just personal preference, but I WANT to see the lapels of a dark suit in a movie... if it's detail that is there [part of the picture] and I can't see it, I feel cheated. So I always end up turning my bright up a little more
Good luck with your tuning, let us know how it goes
