I knew very little about how DRM (in this case, CSS) actually works and how to break it. I tried to operate directly on the VOB file with `ffmpeg` or `mpv` but both failed with a lot of header errors — I suppose more files than the VOB are required for authentication? Whatever, maybe I’ll learn the details in the future, but I don’t see the need since DVD is an outdated technology anyway. So, can we proceed from here? Most certainly. I noticed that although `mpv` won’t let me play a single VOB, I can simply hand it the DVD mount point, and it will play the whole DVD seamlessly. **Caution:** `mpv` needs to be compiled with `libdvdnav` and `libdvdread`!
