Hi Klaus,
The playvideo(url) action seems to not works properly:
- The new video plays but without audio 
(this does not happens in hotspot)...
- The new video displays at lefttop of the plugin with a width and height of 320x240 but the plugin itself continues with his original size ...
A way to avoid those bugs is removing/adding the plugin for each new videos... doing so the playvideo(url) action works correctly...
The time variable has always a value of 0 (this does not happens in hotspot)...
SAlut.
