hello. a few months ago i purchased the Onkyo ONK HTS650 home theater system... i haven't had the problem i've been reading about the sub not working correctly... but i have had a problem with something else. it's really kind of strange becuase i only have this problem with Warner Bros. movies. what happens is i get a quite loud clicking sound... particularly with movies like The Matrix... at first i thought it was something with my speaker wires, but that doesn't explain why it only happens with warner bros. my next theory was that it was my dvd player... but i've since gotten a new one (Sony SON DVPNS715P) and it still happens. and finally i tried a couple of different digital audio cables. a $40 monster cable optical audio cable, and a $65 monster cable coaxial cable. and it made no difference. i'm completely stumped about this... so if anybody has any suggestions i would greatly appreciate it. thanks a lot.
