Magento youtube plugin

I need a plugin for a new magento store, to show youtube video's on it. I prefer it to not show related video's when finished, don't know if/ how this is possible, but would be a big plus if you know a way (for example catch video play time/ enter video playtime and close popup. script might need to know if video is loaded and playing) Below the images there must be a video's section, buttons as big as the small pictures, where customers can click on. When they click on it the video must show in a popup. The popup must appear/ disappear in a nice way, for example with jquery. In the backend, when managing a product, a new section needs to be added where youtube video's can be added and/or deleted. Youtube video's often get deleted or user accounts closed, therefor I would like a way to automatically check if a video is still present once in a while, and disable the video if it's gone. I do need a notification of this so I know that I need to replace it.
