DVD audio skips

Created a DVD file (Share->DVD)and playing the output back in Quicktime, I find the audio music file is skipping (video is smooth).I’ve tried every DVD option with the same results. TheShare->Apple TV output does not skip, but I can’t use that to create a DVD copy. Using the Demo version for FotoMagico 5. I have OS 10.11.4, 3.5 GHz, 16 GB memory 1600MHz DDR3, Graphics card AMD Radeon R9 M290X 2048 MB. Please advise. Thanks! Love the product; hopeful customer - Bob
