I recently purchased the Spears & Munsil 2nd edition calibration disc. The results I'm getting for contrast and color saturation are pretty different than the results I get using Disney Wow. Contrast using S&M is -17 while with Wow it is -2. It's a big difference considering my projectors contrast setting can be set anywhere from -24 to 24. I've made sure my projector is in the same color mode and its power is set to eco every time. Also, I make sure the projector has been running for at least an hour to warm up before calibrating. After calibrating with S&M , I popped the Wow disc back in to see how the contrast setting would look on Wow, and it obviously was way off according to the Wow test. Basically what I'm asking is what calibration disc is more trustworthy? The results I get using Wow and the home theater maximizer on Pixar blu rays are the same, while S&M gives me different results.
