i used the thx optimizer in the finding nemo dvd extra's to do my speakers, and also my tv's picture settings in my house to.

its great, it does front right front left balance tests, front right and rear right, front left rear left. centre, front right, centre front left. a complete bass sweep that goes EXTREMELY deep. i thought my sub was going to explode. if youve got that dvd pull that out, or see if you can borrow it from someone. its a great way to tell.
