I wasn't trying to go off topic, just trying to understand the issues you are having. I typically test my courses on an older ipad over a pretty slow connection and have not had those problems.

Are you able to play HD youtube videos from the devices in question? If so, then that should give you an idea of their capabilities. It's hard to answer your question because there is such a wide range of video sizes and video bitrates, that why I recommended a streaming service like Vimeo which may use adaptive bandwidth and might be able to detect if the device hardware is having trouble playing the video.
