How do I remove the host thumbnail when playing back a video clip full screen in a webinar?

[Giles]

I'm trying to play an intro sting  full screen for a webinar and then appear as a moderator but my host thumbnail's permanently on display in the top right hand corner. Can it be switched off during the video

playback?

Firstly i hope you are using advanced\video.  Secondly turn off all video's until you are ready to start your webinar.
