I made a really long post and for some reason it didn't save or post.. So...

I have a stack of DVDs that keep failing.
These are new, unblemished DVDs that work find in the DVD player and are viewable when I look at them in Windows Explorer..And I am running as Admin.
I've gotten a few hundred DVD to work fine, but lately the last few just don't. They are 'Older' DVDs so one would think any encryption on them would be easier to break then whats on newer ones?

Yet fail to Open with MakeMKX... DVD Fab... VLC... or VideoByte Dvd Ripper... (I figured would try a few others out there)

Snakes on a Plane gives me :

When I put the Disc in even before I ask to open it.

DVDs I've had issues with :
Blood Diamond
Grease
Grease 2
Equilibrium
Little Children
Martian Child


I'm on DVD 200ish of a collection of 5k dvd/BD... so I'm looking to figure out best practices as well.

Errors like that indicate the drive was unable to correctly read a spot on the disc. You can try gently cleaning the discs. You can also try them in a different optical drive if you have one handy.

Most DVD/Blu-ray players that connect to a TV are programmed to blow past read errors and hope you don't notice. MakeMKV is designed to make a bit perfect copy of what's on the disc so if the drive stumbles, MakeMKV will fail the rip.

MakeMKV can use more than one optical drive at a time. Turn on Ask for single drive mode in MakeMKV's preferences and then you can 'lock' an instance of MakeMKV to a specific optical drive. Having multiple drives could be a big time saver for someone with 5K discs to rip!
