Would the Video Essentials or AVIA DVD give me the SAME results, instead of using the Harman Kardon AVR65's built-in pink noise?
What I'm confused about is if I use a dvd's test-tone...each device that I have is different in volume output...like from my digital cable, my Xbox, Gamecube..etc...will any of the sound quality be drastically lowered now, since I used a DVD To calibrate the speakers, and not my receiver's built-in test tones?
