when you transfer video through firewire, it ends up exactly as it is on tape. It's transferred losslessly.
DVD players can't play this, they can only play mpeg1 and mpeg2.
You need to convert to mpeg2, generally, so quality loss will occur. The problem you're having is that the audio is bad quality. What encoding settings are you using?
