Pictures not found

I just got my WD TV live hub and i was quick to upload all my pictures to watch them on the tv. But i realized that the hub only found like 25% of the photos. All the photos are from the same two cameras and in some folders i can only see the photos from one of the camera and some folders i can not even see!?

I can not finger it out, can someone help me please?

Thanks

Jens

Are you connecting this camera directly to the hub or are you using Usb or a external drive?
