Embedding Youtube videos into your website can be a dangerous thing, as it might not be you that's uploaded a copyright infringing video, but it can be you that accidentally embeds a Youtube clip that is infringing made by someone else, into your website. The law against this is: Any time you incorporate a copyrighted work into a site without the rightsholders' consent, you're potentially liable to be sued. Because people are seeing that on your website, it doesn't matter if it's on Youtube or not, or whether you made it or not, you embedded it somewhere else. It also does not matter whether the person knew it was copyright infringement or not. If an innocent embedder were to be taken to court, they could still be fined up to $30,000. However, because of Youtube's copyright infringement policy, it can remove the copyrighted work from Youtube and the websites it was embedded in. Also, there would be little gain for the rightsholder if the person with the website they sued couldn't afford a lawsuit, which would hardly be worth their time. Also, there are precautions that the embedder should take as well, to ensure that even if they do post copyrighted material, they won't really be potential candidates to be sued.
