Hello

I tried to use the Youtube (from Media) to display a video. It works fine ... but it's not possible to have this video autostarted when page loads.

I've set Autostart to "true" in the Property Inspector .. but !!! No results .. the YT video has to launched manually

Some browsers intentionally block 'auto play' when the video has audio.
This is a browser 'feature'.

Also, note that auto play is standard YouTube functionality, this is not something specific to the QnEWB.

wingo: Put yourself in the shoes of your visitor:
Autostart videos and autostart background music are considered as bad Web Design practice!
