Re: Removing DRM from mp4 with no loss(Removing copy-protection from iTunes m4v TV Sh

DRM-protected files are usually encrypted. Removing DRM is not just a question of learning about some proprietary format.

Another problem is that you can convert MPEG-2 video to DVD losslessly, but you can't convert MPEG-4 or MPEG-4 AVC (h.264) videos to DVD losslessly.
