If you do that, you might want to add a message saying that you disabled all JS functionality on the site because of DNT, because it is not something users would expect to happen. If I set DNT and go to youtube.com, I would expect to see video anyway. The same for embedded videos on some blog. I am not saying this is a bad way (it is much better than many others), just that users should be made aware of the cause.
