Lightbox swf files

Hi,

i am trying to load a swf into lightbox the whole day.

i use this code
<a rel="lightvideo" href="sites/default/files/whatislove-mega-collection.swf" class="lightbox-processed">default size</a>

i use JW player, because no other worked (flowplayer3 i tried too). if i load an *.flv the player opens it and its working but with the swf...he´s loading the startscreen but no interactions with the buttons are possible. its a game in swf format.
and i already searched but found no solution. Any suggestions, im clueless.

I also have swftools installed.

thank you

marco
