If you're experiencing rip errors, please read here first!

I'm sorry guys... I'm at a lost... I have two different drives and they both give the following errors with Avatar, The Way of the Water.
-Scsi error - MEDIUM ERROR:L-EC UNCORRECTABLE ERROR'
-STATUS_DEVICE_DATA_ERROR' occurred while reading '\Device\CdRom0'
- MEDIUM ERROR:L-EC UNCORRECTABLE ERROR' occurred while reading '

I swore I ripped it in early 2025 on a different version and now on 1.18.1 But now that I'm trying to rip it again (To have a Remux copy), I get the above errors and don't know why.

Also have done the lastst Find VUK as of today with no luck. Any help would be great.

Those mean the drive is having trouble reading a section of the disc. Try cleaning the disc before attempting to rip it again.

I have tried that... What bugs me is that the disc as clean as I can get and BOTH drives are having the problem.... Driving me nuts!

Today i got a UHD disc that shows me many of these m2ts errors and cant be ripped.
The first information you get here is to clean your disc.
Ok sometimes there are fingerprints or dust on a disc but sometimes the disc is clean and you got also these errors.
First i thought that the disc was defect.
I testet it in my StandAlone Player...it works.
Ok, ripping with makemkv an wantching in a Player is not the same, so i take the disc put it in the same drive and tested it with VSO Inspector. VSO Inspector cant find any errors.
After that i searched the net, every time you can read that the disc is defect or must be cleaned.
After that i put the IO settings to a higher level than 5 after that i added this to the mkv registry (you find it under KEY_CURRENT_USER):
io_IgnoreReadErrors
you must create it with DWORD and activate it with 1
After that i try the same disc again and got the same m2ts errors but now the disc can be ripped succefully.
I tested the mkv on my vlc and the movie plays without any errors.
So whats going on here? When so many m2ts files are really corrupt because of dust or a disc defect it is absolutly not possible that the ripped mkv file worked without any issues.

Has anyone had this issue with Back To The Future?

It's not so much dust or a defect (yes, there are quite a few defective UHD discs about). It is more the fact that most UHD discs have an invisible layer of film on them from the manufacturing process that needs to be cleaned off.
