Hi, I read in a Home Theater magazine that the folks at this company use the Spears and Munsil High Definition Benchmark Blu-Ray disc to calibrate each HDTV before they do a review on them. I found that to be pretty interesting so I ordered one to try out. I see the reviews on Amazon show that about 2/3 of the people who bought the disc loved it and 1/3 disliked it. I also see it comes free with any Oppo Blu-Ray player purchase. I was wondering if anyone would care to give their 2 cents.
