Pioneer DVR-106 from Dual G5

The Dual G5 is supposed to be equipped with a Pioneer DVR-106. This DVD Burner normally support DVD- and + R/RW medias.
However, according to Pioneer source, Apple would have flashed them so that they would not burn +R/RW medias.
The DVR-106 currently has Firmware 106, while the ones in the G5 have a special Firmware verison A606. We can surely install another Firmware on it to make it accept the +R/RW medias. We will try that as soon as possible.
