I could see it being a hassle if someone made a DVD that fully utilized menu-ing to create an interactive choose your own adventure DVD. Or prune out all but the longest video streams to eliminate previews, etc. It can ‘discover’ hidden video segments, and you can choose to skip audio tracks you don’t want. MakeMKV is one of many workarounds out there which began with DeCSS (Google That), and I find MakeMKV actually more useful than ISO files to copy DVDs. They are working the way their treacherous manufacturers intended, and that is wrong. And all other DVD/BluRay drives you can get your hands on will also be wrong in the same way. The drive has decided to not give you the data because its manufacturer, Phillips/Sony/Adaptec/whoever made an agreement with the MPAA that prioritized their interests over your own.

Now the ATA protocol doesn’t have a ioctl like FU_Peasant, so it just throws I/O errors. What insufferable peasants of a users we must be.īut dd doesn’t have those keys. And it will do so, in entirety, if an equally treacherous software program executing in your OS environment (say, WinDVD?) commands the drive to do so and its command is cryptographically signed via keys that are withheld from you.

And this software has the keys to decrypt them. Your DVD drive runs software internally (maybe you’d be more happy to call it firmware) that recognizes encrypted discs.

How sad that you’re so confident, because you clearly do not understand how CSS works. Why doesn’t it just copy? Not read and not like, and so spit out garbage or break. Why is it not wanting to copy? It is “looking” at something. There’s no DVD damage and no DVD-R damage. If I didn’t use the conv or status flags, I would get IO errors to stderr. This is the only thing I could use to get no errors. So I tried this ĭd if=/dev/sr0 of=file.dat conv=noerror status=none And I have plenty of DVDs of my own around. I have a video dvd, I rented the other day, I know, there’s copyrights, but I wanted to watch later. I don’t want it encrypting or decrypting or altering or converting (for example into an ISO) my data. Firstly, I do not want dd “judging” bits. Do any of the ‘dd’ users out there like me know the answer to this situation. It has always been my understanding, and perhaps I am wrong that dd would always copy a bit for bit stream to another location, be it file or device.
