If you are looking to build a tube porn site then you can't go past WP Script. It will enable you to even just embed videos from the major tube sites if you don't wish to host videos. Have a look at Makefuck.com for an example of just how powerful it is.
If you set it up correctly you can even block popups and redirects to the porn site that you are using their videos from. So you are basically hosting your own videos without paying the bandwidth costs.
You can also then scan all your embedded videos to remove any that have broken links to the videos. This will save you countless hours or even days trying to do it manually.
