About synchronizing video streams across multiple devices, I am not familiar with this topic so I cannot really help. I am sure there are ways to do it (E.g. services which allow you to watch a YouTube video in synch with your friends) but due to latency and other factors I don’t believe it can be 100% perfect. At least this has been my experience.
