I seem to remember that if you have a dvd disc which has the THX logo on the cover then go into the dvd films menu select the audio or THX option and you can use that its the same as doing it from the proper disk i think . I seem to remember using Star Wars to setup a TV for a friend and its saves you buying the proper disk so check you film collection!!!
Made by the good people at Monster Cable.
After running through that to get the basics, I use a Spyder 3 Pro device.
Doesn't get more accurate than that.
