The AVS HD709 disk is available free from AVS. I don't have the link off-hand but if you use Search, you can find the download links. The other disks like WoW, Spears & Munsil, DVE, etc are commercial and you can find them online to purchase. While these are called calibration disks, you won't be actually calibrating your tv. A true calibration requires the use of meters and specialized software. You can DIY, but it can be expensive and there is an extensive learning curve, or you can pay a professional calibrator to do it. Using a disk alone may be all you need. The nice thing about using a disk, is once you learn how to do it and what the different settings mean, you can always fine tune your tv as the components age and keep it looking great. With a professional calibration, you may have to pay again down the road depending on the calibrator and how long your tv will hold the settings. I used the AVS disk to get me going but i think WoW is supposed to be the easiest for the newcomer. Whichever disk you use, stick with that one. Patterns etc may vary from disk to disk and you may get confusing results if you switch between disks. There is lots of help over in the Display Calibration forum once you get started. Take your time, organize yourself, and always write down settings before you make changes should you not like the results and want to go back. All of the settings you need should be available to you thru the user accessible menus. You should NEVER have to go into the Service Menu to make changes. That is the quickest way to permanently brick your tv.
