The DRM buttons in the TCCP Project folder are only for the creator of the assets(s). It turns the ability to download them from the DLC Content Store. They do not effect the end user. What does effect the end user is the TCCP Project List under Edit Project. The first box is Featured Assets, the second box is Assets to be payware encoded.
By not encoding the asset, you are leaving it unlocked, which I thought was meant by the DRM button on the TCCP website. So just a not very well documented interface, but by trial and error, you start to see it.
