theres a mail looking tab after ya view the video, you can email the link or sms to someone, through there when they click it itll open up their opera browser and open through your media player, but as far as it opening in the youtube app the best bet would be send em the link through that mail tab and when they open it they will see the title of the video, then they can open their app and search.... those are the only way ive heard of..........
