Ubuntu 24.04
MakeMKV 18.4 Linux compiled from source, from this website
BU40N with 1.03 firmware (reflashed from 1.05, which was original)

Problem: Linux cannot read the disc and keeps skipping, restarting, retrying. But windows 11 can read it with same drive , no problems.
Is this because of the firmware 1.3. I read that Windows works better with another Bu40N firmware.

I still have a windows 11 laptop, but mainly use my Ubuntu nowadays.
Should I reflash? Or was this movie "Fury of the dragon" released by DFW Dutch film works DVD a one time fluke and I should not bother reflashing?

Thank you in advance.

There have been saying that BU40N needs 1.00 to work properly (in some cases?) in Linux. Not sure if it's true for DVDs though.

Can VLC or mpv (with libdvdcss installed) play the DVD? If so maybe you'd want to try dvdbackup.

dvd backup is the name of the linux program?

Yes (without the space).
