Remove copy-protection from DVR-MS files

I'm trying to remove the commercials from some TV shows recorded with MCE2005 dvr-ms files and then archive them. However, some shows show as copy protected and won't let me edit them.

Is there a way to strip the protection from the files so I can edit and archive?

Thanks for your help!

There are only 2 programs I know that can remove DRM protection from video files: FairUse4WM and Tunebite.

Both require playble media files with working licenses. And they doesn't seem to support DVR-MS files.

If you can play the files, the only thing I can suggest is to use a screen video capture program. Such programs can record video from your screen. Many of them can record audio as well.
