There seems to be a problem with the featured media (video). It doesn’t play. See example: http://detag.me/members/admin/
However, if you go to the single media page for that exact same video, it plays fine. See example: http://detag.me/members/admin/media/20/
Also, you’ll notice the video seems to have been uploaded upside-down (rotated 180 degrees). On my computer using Quicktime the video plays the right way.
