are you limited using a URL to post the video to DU
and how does one save the stream or find out the url of the video?
on edit - so I read instructions as a last resort:
1. VIDEO FORMATS
Your video must be hosted at YouTube.com. The DU Video Forum does not currently accept video from other sites. If you have a video from another site, you'll need to upload it to YouTube before you can post it in this forum. See YouTube's Help Center for more information on how to upload.
2. HOW TO POST IN THIS FORUM
After you click the "Post" icon at the top of the page, you will be asked to submit the URL of your video. Go to the YouTube page which contains the video you want to post. In the box to the right of the video, just beneath the "Tags" section, you will see a textbox marked "URL." Copy the entire URL from that box, and paste it into the Video URL box on our Post page. YouTube URLs look like this:
