Is there any reason why some videos on YouTube come up with this phrase. This is my wife's YouTube channel and some of her videos work and some do not. She's a Zumba instructor and all her videos have music to them and in the subject. I know YouTube is strict now on music being posted for copyright purposes. But the same video works on my wife's Windows phone and my daughters iPhone. Not sure if it's my phone. But other videos play from my wife too on my phone with no problems . Just some do not.. Any help? Thanks
