So I collected old home movies and edited them in iMovieHD. I proceeded to transfer that to iDVD and customized it there. I played it on iDVD (I didn't save it as a disk image) and the audio and everything else worked beautifully. When i burned it onto a dvd, the dvd would play but no audio in my DVD player. Thinking it's my DVD players problem, I tried it on my Macbook and the audio failed there too. I tried looking for threads about this but I only found help if the audio is iTunes music. My audio is already in .aiff format. Thanks!
