Audio problems with dvd
 

Im using final cut studio and i have dvd studio pro and compressor and I havn't yet figured out a way to make my music sound good. I make short surf films with surfing video and just a song the whole way through and when I make a dvd adn play it back on a tv it doesn't sound to good. Im getting my music from my itunes. Anybody have anytips on how to fix this and give me better sounding music on my dvds.
