Hi,
about 'blurry' - you see only the preview pano, because there are no <mobile> or <tablet> images in the xml.
About the video - remove the parent="" for the video element - or update to the latest version.
There was a bug with empty parent settings - the old viewer version wasn't checking if the setting is empty and so it keeps waiting for an element with that (empty) name, but such element will never appear and so also not the video.
Best regards,
Klaus
