[G4] PIONEER DVR-109 "NOT SUPPORTED"

[DARRYL SPESSARD]

Yesterday I installed a Pioneer DVR-109.  Previously I have had 3 
different Pioneer DVD recorders installed in my Dual Mirror Drive 1GHZ 
Computer.  All were plug in and go. The last was a DVR-105 and worked 
without a problem.  Now with the DVR 109 I see that disc burning is not 
supported.  I did however check Toast and recorded successfully a 
complete disc with no problems.  I am running 10.3.9 and had firmware 
1.40 originally.  It said Disc Burning Not Support so I upgraded to 1.50 
then to 1.55.  Each time there was the same results "Not Supported". 

Please advise why the DVR 109 is not recognized by System to record discs.

Assistance would be greatly appreciated.

Thank You, Darryl
