Pioneer 109 burnfailure at the same place every time

Hi every one,

Sorry this is my first so please bare with me.

I’m having huge problems burning with my 109. I have the latest firm ware 1.58.
I’m using Ritek DVD-R 8x full face printables G05. The burn fails at the same point every time, about 8mm from the outer edge of the disk. Now, i’ve had this burner about a year now and have always used this media. I had this problem a couple of weeks ago and didn’t really sort it because i just started a new spindle of media and it started working again. But now it’s happened again, so i started another spindle and thats doing the same. And the discs are fine when burning with my old liteon burner.

Please please help.
