After Xfburn starts writing, it gives an error message: ** (xfburn:16787): WARNING **: [FATAL] 131357: SCSI error on write(32,16): [5 24 00] Illegal request. Invalid field in cdb. (0) I use Arch Linux. xfburn version 0.5.4 for Xfce 4.12 'cdrecord -v dvd.iso' writes correctly the iso.
New version of xfce and xfburn is out in the arch repo please upgrade and see if its still an issue.
No new information I'll assume it has been fixed for you.
