Not yet. Just played around with the settings a bit. I have Digital Video Essentials: HD Basics Blu-ray (2008), but haven't had the time to do it yet. I used it on the smaller TV, but wasn't pleased with the results. I ended up using the "Standard" pre-set instead. If anyone knows of a better one, please let me know.

But, I don't think calibration will take the light out of the black bars and remove the occasional grayish overcast from the screen in a dark room.
