No sound on burned DVD, but I have the codecs (I thought...?)

I recently figured out how to finally burn DVD’s (thanks to Frank ) and have gotten about four copied perfectly (using WinAVI, DVDShrink and DVDdecrypter.) Well now I’m on my fifth DVD, and everythign burns fine, except for the fact that the sound doesn’t work! I have the necessary codecs, because it works fine straight from my HD, it just doesn’t work once on a DVD.

Is it possible to need specific codecs just for the DVD? Or if it works on the computer should it work fine on the DVD? Any help would be GREATLY apprectiated.
