iTunes DRM seems to have defeated all stripper utilities

[deadman]

From what I can tell, no program for stripping the DRM off an iTunes .m4v video file works now. I tried TunesKit and a number of others, all produce similar output - a file with audio and subs but no video. I can't even use older versions of iTunes as they're no longer compatible with recently downloaded files. Only newer versions that the stripping tools can't work with will play downloads anymore.

Does anyone know of a utility that still works?
