Many thanks to all for this help an tips.
First I installed the Betaplayer to show the .mov Panoramas and...
well, there is a small stripe on the screen in which the player plays the Panorama as a video.
So I can't move the Panorama on my own and its not the real size.
But its the first player which opens .mov files.
Next I'll try OddbOd's Idea...
I suppose you could extract the panorama with something like Cubic Converter and re-author it using a Java based panorama viewer like PTViewer though I have no idea whether this actually works.
All in all...
thanks a lot for the great help, its a great ppc forum!
