Looks like they are using the Media RSS extension which we only 
partially support. We assume that anything in a media:content section is 
a video we can play but in this case they contain images. We should be 
using the 'medium' or 'type' attributes to filter out anything that is 
not a video but we don't. We do extract the 'type' but don't do anything 
with it. I would be easier to use the 'medium' attribute and just ignore 
anything that isn't a video. See 
http://www.rssboard.org/media-rss#media-content for details.

At least you can download the feed it doesn't work at all here using 
master I get this error NewsSite: HTTP Protocol Error  Explanation: 0: 
Moved Permanently when I try.
