dvd+rw blanking

[david walcroft]

Hi,
   I use a pioneer DVR 108 dvd burner (dual layer) and I can not blank a 
+rw with
 xcdroast or cdrecord,as root I get in FC3 xcdroast

"cdrecord.prodvd: Cannot blank with non Ricoh based drive.
cdrecord.prodvd: Cannot blank disk, aborting.
cdrecord.prodvd: Some drives do not support all blank types.
cdrecord.prodvd: Try again with cdrecord blank=all"

In # 'cdrecord blank=all'  I get

Starting to write CD/DVD at speed   2.0 in real BLANK mode for single

cdrecord: OPC failed.
Error: this media does not support blanking, ignoring.
This drive or media does not support the 'BLANK media' command
cdrecord: Cannot blank disk, aborting.

Looking at that its saying the drive is only a dvd-rw when it is a +rw 
having burnt
a FC3-t3 Iso to a +rw.

  Thanks    david
