It seems a few dvds I watch the vocals seem to suffer slight distortion (independant of volume). It's noticible when people shout, theres a slight popping. I have recently replaced all my equipment apart from the speakers and I noticed it in the old setup also, thought it may be the speakers but the distortion is present in headphones also. It must be the recording on the disc. All other loud sounds, explosions etc. seem fine. Other discs, such as gladiator also have no problem. My gf never picks up on it but I notice, anyone else? A few discs I can (vaguely) remember are; Exit Wounds - Near the end when they all meet up in the warehouse before the final 'showdown', mainly when the fat ploice chief raises his voice Kiss of the Dragon rental - The scene where the bad guy meets the chinease police chiefs(?), particularly when he shows them the surveilence photos.
