My First guess would have to be the movies source.  It's highly possible that this movie wasnt encoded well, meaning that the problem is not with your hardware at all.  Are you downloading the movie, or "streaming it".  If your streaming it, it's very possible that it's related to the speed of your internet connection.  

Onboard sound is not the greatest, but should be more than adequete for most applications, and shouldnt sound scratchy, be full or pop's or hisses.  Make sure your speakers, and speaker wires are isolated from as many other cords and cables as possible, including walls where electrical may run behind the drywall.  Make sure you have your speakers pluged into the correct jack on your sound card.  If your using a single input to your speakers, they are usually green to green. Alot of sound cards have digital outputs, line level outs, and center and rear surround outs.  Consult your manual and make sure everything is where it's supposed to be pluged in at.

If you find out more details, post again, will do what I can.
