Old enough for a drive to go blind.

So it's not the fault of the software alone.

It might really be about manufacturers. (Brands are not
very reliable indicators about the real factory which made
a DVD-R medium.)
It might well be about the difference between DVD-R and
DVD-RW, which use different chemicals to react on laser beams.
(Normally it's DVD-RW which fail first on aged drives.)

This may be an incident. The drive might have gone ill
around the time when you changed operating systems.
Did you use the driven often before the change ?
It may also be caused by the Windows burn program using
one of the DVD-R write types "Incremental" and "DAO" whereas
Brasero and xfburn may have used the other.
What happens if you let Brasero write the ISO into an
image file on hard disk (e.g. "image.iso") and then let
cdrskin burn it to DVD-R ?
Install package "cdrskin" and run it in a shell terminal
Once with write type "DAO":
cdrskin -v dev=/dev/sr0 -sao image.iso
and once with write type "Incremental"
cdrskin -v dev=/dev/sr0 -tao image.iso
(Note the decisive difference between "s" and "t" in "-sao"
Does one or both of these tries succeed ?

Burn programs and drives have a client-server relationship.
The burn program sends SCSI commands and the drive firmware
decides what then to do with the medium.
This is well standardized. There are no DVD drives known
which would not obey the SCSI command set as described in
documents SPC-3, MMC-5, and SBC-2.

The Linux kernel takes care of the SCSI commands and transmits
them via the bus (USB, SATA, PATA, ...) to the drive.
Inside the USB box there is probably a SATA attached DVD drive
and a USB-SATA bridge controller.
The Brasero log shows no indication that this transmission
would have problems. The error code "3 0C 80" is the SCSI
"Sense Code" as returned by the drive. It means that the drive
accuses the medium of being bad.
This accusation is probably wrong. I'd rather expect the drive
to be bad.

Make above two experiments with a ISO image file. If one of them
works we can try to talk Brasero or xfburn into using the same
If the other fails, then you have reason to mistrust the drive.
Both should work if drive and media are ok.
Have a nice day :)
