I agree with the previous answer, but I just thought I'd make it a little more clear, because I had the same problem. First go to YouTube and find the video that you want to use, then click on "embed" and go to Edit in your browser and copy it. Then go back to your hub and add the video capsule and click on edit, then click the URL box and go to Edit in your browser and click paste then go back to the URL box and paste. Voila, you have your video. Hope this helped. If this doesn't work, I might have missed a step, please let me know.
