Oh, thank you, thank you! What was I doing wrong? I tried three times and gave up in frustration. First, I copied in the HTML directly from the DailyKos diary, where the videos were working fine. The preview showed all the HTML coding (for the videos, and not the rest of the diary, which looked fine). Then I went in and removed all the attributes, and the preview still showed all the HTML coding. I copied in the HTMl direct from the yourtube link for the Black video, and it looked correct, but still did not work. So I gave up and left the request for help. So, i do not mind at all; I'm very grateful.
