Picked up my oblivion game today and on the opening scene emperor speaks he keeps cutting out, and at thye begining when Bethesdas logo comes onscreen the music cuts out a little the game runs fine but just wondering if that has hapnened to anyone else?

The emperor movie on mine is really wierd, like big squares cut out and stuff, but then the game runs perfectly, also If I try to load the bink on its own (outside the game) it works fine
