stock, these videos are not showing, not sure why????
The video hosting sites can be quite finicky about playing videos framed at another site via media tags - especially for users that are not logged onto the video platform.
Sometimes when a video is relatively new they will allow anonymous remote play - but only for a short period. This can be frustrating in a Forums environment because a media tag may initially work and then subsequently fail after the editing window is closed. In such cases even the url to the video is lost. When remote play is blocked at Post Time you get the result we see here where the media tags print as texts and the URL turns into a link.
This is why I typically don't use the media tags for video and instead embed links in the posting.
