Digital Video Essentials was pretty much the only legitimate option when it came to calibrating via Blu-ray player. At long last, a little competition has stepped into the field. Stacey Spears and Don Munsil -- creators of the DVD Player Benchmark and Progressive Scan Shootout at Secrets of Home Theater and High Fidelity -- has just released the Spears & Munsil High Definition Benchmark: Blu-ray Edition. The disc is chock full of test material and calibration patterns to help HD junkies adjust their home theater systems for optimal playback, and according to co-creator Stacey Spears, all of the material was created from scratch. Coincidentally enough, this very disc was bundled with our OPPO BDP-83 test deck, but given that it's on sale now at Amazon and direct from OPPO, we suppose that's not too terribly shocking. MSRP is pegged at $24.99, and you'll find lots more details waiting in the read link.
