When a post is added to the root site, it becomes available to all of our sites in a library. Users can repost to their blog. However, if there is a video embedded (using plain text link or embed code) and the user is NOT logged in as a Super Administrator, the link code is stripped out. I've tried a plugin (Viper) that embeds videos and that didn't help either.
Is there something in the Admin role in multisite that would be disallowing these video embeds?
