This DVD does not play on DVD players. When I started the DVD, nothing would happen. None of the menu options would play. I finally got it to start playing only to have it stop a couple exercises later and then the DVD refused to play. I tried the DVD again and again and had the exact same problem. I cleaned the new disk and my DVD player, but that did not help. I have never had a problem with my DVD player. I have an expensive multi-region DVD player which easily plays DVD's from around the world, but it would not play this DVD. I even tried it on my two of friends' DVD players, and they had the same results. The strange thing was that I easily could play it on my computer which makes me think that who every produced the DVD did not format it for DVD player use. The couple of exercises I could get to play looked wonderful and the music was great, but I wanted to be able to use the DVD as a do-along-class and cannot do that if it will only play on my computer in my small office. I would highly recommend this DVD from what little I saw if it actually would play. I did contact the seller and they told me that they would replace the DVD and that they have never had any problems before. I guess I will see.
