I have an old iMac running running devuan jessie. I couldn't burn DVDs
using xfburn. It appears to be a known problem on early Intel Mac mini
and Mac Pro. The error message is:-

WARNING **: [FATAL] 131357: SCSI error onwrite(32,16): [5 24 00] Illegal
request. Invalid field in cdb.

The solution was to download the following files from a debian sid
repository:-

libxfce4util7_4.12.1-3_amd64.deb and xfburn_0.5.4-1_amd64.deb

use dkpg to install them.

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=775086

has the full info but the original bug reporter never responded to
requests for logs.

The interweb had two options namely downgrade to xfburn 0.5.0 or upgrade
to the latest xfburn.
