Hello every buddy, in Germany we have an online Disk rental service called Videobuster, and I was wondering if it is possible to rip a rented Blu-ray with MakeMKV.

Yes I know this is not how renting a Blu-ray works, but I just want to know if anyone has experience with this.

Thank you.

Of course it is but you have to be aware of the legal situation in your country. In some personal backups of owned discs are allowed like in the US. Not so in Germany and ripping not-owned discs is unlawful pretty much in any country.
