You tube videos wont play continuously, going from play to stop after a few seconds. I click on play and after a few seconds it stops again. It does this whether I'm on wireless or 3G on my iPad 2. It does this when I use YouTube app or through Safari. I have most updated version on my iPad. When I first bought my iPad it would play entire YouTube video but not now. I must have messed up some kind of setting. Any ideas?
