My Wifi network is always used for my iPad2 and iPhone4 when I'm at home. Even though I can stream movies through my router to the TV without any problem, the iPad2 is a dismal failure even for mini-vids such as You Tube stuff. I have to keep pressing the play button every couple seconds to get through any videos. Yet, the iPhone4 is flawless on the same system and even in the same location as the iPad2. What's with my iPad2? Is there something interfering with video downloading and playing? It appears the download process doesn't keep up with the speed of the video.
