I burned a DVD with RealTimes (RealPlayer) and when I play it back, the audio keeps fading in and out. How can I fix this?

Audio problems during playback may be caused by an incompatibility in the original file format. Try first converting the file(s) to MP4 or WMV, and then burning the DVD. The conversion should resolve the sound issues when the new DVD is played. See  Convert video files to play on other devices for step-by-step instructions on converting video clips.
