Just downloaded makemkv and it failed to open the disc. The error information was as following:
MakeMKV v1.15.1 win(x64-release) started
Downloading latest SDF to C:
Automatic SDF downloading is disabled or failed.
Using direct disc access mode
Downloading latest SDF to C:

Failed to open disc

What is the problem?

The inability to download the SDF file should be addressed, but it does not affect DVD operation.

What is a problem is that your drive cannot read parts of the disk itself; usually this is because of contamination on the disk, or even scratches. Cleaning the disk is your first step.

i ripped my first 4k disc, now any disc i insert makemkv say " No Disc" after loading

"No disk" means the operating system doesn't see the disk change.

If you close MakeMKV and restart it, does the disk load? Can you access the disk directories using Explorer?

I got it. Apparently plugging back in my burner it updates it so I had to flash it again. Any idea how to avoid it doing that again?
