Perhaps this is an issue with videopress, I’m not exactly sure, but if you go to this link -http://studiotwophotography.wordpress.com/2012/09/18/extended-family-north-vancouver-family-photography/
you will see that the black video background appears above the top image and then the video cover appears at the bottom.
I don’t know if there’s a way to fix this, perhaps it just needs re-uploading?
I think you have some HTML issues on your blog, not uncommon. Go to Settings->Writing and select “wordpress should correct invalidly nested XHTML” and save changes. Then edit that post, making any kind of change at all, and update. That should fix it.
