Audio messed up on burned DVD using Nero 7 Essentials


I burned a DVD +R video and when I play the DVD on my home player, the video looks fine, but the audio sounds like the chipmunks and there is some hissing noise. I am using Nero 7 essentials burning software and my video options are setup up for ‘Long Play’ and the audio is setup up for ‘Automatic’. Also, I set the DVD to burn at 4X and my media is 16X. Anyone know what is wrong?
