Like Barry said, re-encode it with TMPGEnc (www.tmpgenc.net). It's recommended to make a WAV of the audio first using VirtualDub and then re-encode the video to VCD using the AVI as the video file and the WAV as the audio file. TMPGEnc has a feature that fixes audio\video synchronization problems, so that problem will be gone too.
