I've just bought a Canon HG21. I downloaded the movie clips to Imovie08 and dragged them across to Idvd on my mbpro. Then burnt a dvd-r from Idvd. I can play it beautifully on the mac, but when I put it in the dvd player although the image is great, there's no sound on the tv. What's happening and how can I fix it so I can share the dvd's with family who don't have computers or blue-ray dvd players.
