i just bought the box set yesterday and noticed that the disc 4 looks kind of funny. (the physical disc - it looks like there's an area of darker shade in the DVD surface...) i need to figure out whether to get it exchanged or not, so if anyone else's got one, can you please check the following? on disc 4, the first episode (Burn's Heir), in the opening credit... i can't hear homer yell "D'oh!" when Lisa zips by him as he exits his car. can you? by the way, if anyone's looking to get one, go to a best buy. they have it on sale for $30, which is quite a bargain.
