Can you get brightcove based videos to work? A lot of news organizations use it. Hulu uses it as well. See the link below. I think the difference between HULU and the news organizations is that HULU uses a DNS cname to make it appear that the video is hosted on their site when it is really hosted by Brightcove. Adding brightcove support would make this work with tens of thousands of news websites.
