Hi,
You could doctor them to be compatible. Save a set of scene files on your Euro camera. Open the file with a text editor. At the top of the file you will see a header that identifies your camera. Copy and past that into the file you downloaded over the top of the same lines that id the the US camera. Then as far as the frame rates, wait until you have loaded the file into your camera and then go through the scene file on the camera and set the frame rates you want. Then save it back to the card with the correct frame rates.
Hope that makes sense.
Best,
Jan
