I have both the AVIA and the DVE discs. I also own Joe Kane's original calibration LD. While original LD was wonderful to calibrate analog televisions, the DVDs are virtually useless in calibrating todays DTVs. The directions even left me confused and I am accustomed to using the LD. I suggest that you get yourself a blue wratten filter and use it to do a basic calibration with regular color signal broadcasts. Dont waste your money on these dvds.
