I've been away for a few years....and I know before when I played SL...I had a TV I had made from just a prim and then I put youtube on the face....and I was able to press play....and all my friends who were around me could see it start playing too....I've got the same TV set up and have youtube on there....however, it seems that no one can view it unless they press play themselves....am I missing an option/setting or are they? Thank you!!!
