I've heard that the (of all people) Disney WOW disc is great for DIY calibration. I hope so because I bought it. The others out there seem like just minor updates to the old DVD versions, which who knows if they are an issue or not as I too have the DVD version of a few calibration discs.

Plus, you are right on with this, many people post online the calibrations that they are using, and while there are other factors, like screen gain, etc, but they are a great starting point.
