If I got the solution, then I'll share it with you. Is it okay, to write it as a comment or do you prefer email?

Thanks for your help, I didn't know that the page can only have one onLoad event so you gave me a point where I can start! Have a nice day!

Thank you so much for your quick reply. My main problem is, that SWFObject resides in an external file without any linebreaks or spaces and this file looks like some kind of mess. So If you don't mind I would like to ask you, to take a look at the source of swfObject if you have some spare-time.
