Yes. With this plug-in you can embed many videos from many video sites like YouTube and have total control over them. You can choose to run them one after the other or with a side menu with annotation or make them autostart.
All that without the concern that YouTube might remove your video or offer another video at the end that takes attention from your video etc.
Use one of the many sites to download the YouTube videos to your PC (like keepvid.com), then create the widget with this plug-in and select them.
