I've added a number of NicoNicoDouga videos last night and most of them do not appear to be showing up. One video did show up but the title, description, and thumbnail image did not process correctly. I've looked back at the other NND videos I've added earlier and a video from about a month ago does not seem to embed properly but the video submitted earlier to that one do embed correctly.
