distortion?

[alkalinesi]

hey guys, i need help real fast. i bought 40 yr old virgin and forgettin sarah marshall. you can see my sig for my setup. i popped in 40 yr old first. and the voices didnt sound right, like when ever they hit certain pitches or somthing it would sound like they were yelling into a microphone. it has some kinda ditsortion or somthing very hard to explain. and sarah marshall the same thing just not as bad.(i couldnt get through 40 yr old it was so annoying) now these are the 1st titles i experienced this with and kinda ironic theyre both universal. i popped in iron man and it sounds perfect. so has anybody heard of this prob or have any answers? thank you
