Help - Itune crash while trying to play purchased video

Itunes will freeze or crash anytime I try to play a tv show or movie purchased off of Itunes. I noticed I'm not the only person with the problem. Maybe Apple can try and fix the problem for its customers ??

I have intalled all the latest drivers and reinstalled Itunes and maniplated Quicktime - I think apple now needs to stop accusing the customers and fix the itunes software -

Thank you
