2. Press the 'Edit Button'
3. Click the 'AVI' Tab
4. Change the compression to 'DV Video Encoder Type 1'
5. Check that the audio is set to PCM 44.1Khz (Although dependent upon your camera you may try some of the other options - particularly the 12 bit options if that is what your camera sound is set to).
6. render your movie and re-try
