You can play YouTube media using the Director and the Performance HUD.
Someone asked about ads.
I tried this.
Use Share and grab the link they give you and use that in your *autofx command. It seems to strip off the part that tells it to preceed it with an ad.
Or you can manually change this:
https://www.youtube.com/watch?v=8xk1P1913y0
to this format
http://youtu.be/8xk1P1913y0
Results are the same.
*********************************
ALSO we discovered that if the parcel which the director is on is deeded to the group, then you need to also deed the director to the group. Press the SHARE button first, then DEED. Your group role must have this ability granted. Owners will have this by default.
