Of course, by "removing" DRM, you'd be committing an illegal act and exposing yourself to legal action from Big Content.
If you were smart enough to avoid the whole DRM dance entirely and are looking for a solution to this problem, you may want to check out a free software utility called Briss. I've experienced mixed results personally so I can't say for sure if it would offer a true solution for you.
The utility can be found at
