Saddly, for distributers, there are programs that remove ANY DRM.
Tunebite records the songs, while playing them. And yes, if you burn to a CD, the DRM is removed when ripped to a computer. My sugestion: make the DRM so it can't be burned to a CD. That will help, but there's still Tunebite. Tunebite is expensive though, just for some podcasts. It is easy putting DRM music on an MP3 or iPod. They will play just how they do if you download from iTunes. iTunes uses DRM. So far, I have not found any free easy source of DRM, I actually posted recently. You have to pay per licence (download).
