Pioneer's website for the 103/104/105/106/107/108 DVD+/-R recorders has a more recent version of the firmware. Should I install it?
No! Do NOT install Pioneer's version of the firmware. We have a special version from Pioneer that must be installed for proper tray and robotic operation. If you install Pioneer's version first, you will irrevocably damage the drive. Pioneer does not allow earlier versions to be installed once upgraded.
