Hi

I am trying to back up some of my bluray movie disks and a few makemkv doesn't give me the option to back up which is strange. Are there unknown limits to making decrypted backups?

a few of the discs are LOTR FOTR special features and appendices.

Thanks

Double check that you didn't try to back up a DVD (instead of a Blu-Ray Disc).

Many commercial BD sets come with DVD versions of the extras.

Hi

Thanks for the help, its definitely bluray the disk size is over 30gb, and this set is specifically a bluray set (google the middle earth saga)

when I open the disk it says in the log something like- multiple (something) to scan will take a while. would this have an effect?

any ideas would be great

Thanks

The backup option is only available if the disc is not "open"!!

If that message was like this, that's a DVD, because BDs do not have VOBUs.

Complex multiplex encountered - 1 cells and 1803 VOBUs have to be scanned. This may take some time, please be patient - it can't be avoided.

A quote from an Amazon review:

To be clear, this review is for the Lord of the Rings trilogy bluray 15-disc extended edition box set. The movies themselves are blu-ray, but the extra features are DVD discs, by design, which is ok.

Thanks for this, so I looked at the disc and your right, the extras with the hobbit trilogy are Bluray (hence makemkv had no issues) but the extras for LOTR are dvd format.

Is there an easy way to back up the files of a dvd disk like I was doing for the bluray disks with the hobbit?

Thanks for the help

If your reason for using backup is to preserve menus and such, the "best" way to do a DVD is to save an ISO of it, preferably with the encryption removed. Players can then treat it just like you'd inserted the DVD itself. I've used a program called "BDLot" in the past, which hasn't been updated in a decade or so, but it's still available from several sites for download.

That, of course, is a bit wasteful of space, because there's at least 20% overhead in that, versus creating MKV files, AND you can post-process the MKV files with tools like handbrake to reduce their space requirements.

Some people don't worry about space, but... I have 70TB available, and I just had to do some clean-up to get back down to 35TB in use, so I still worry about space.
