Poor burns with Pioneer DVR-109 using TY media

Look at this.

It can’t be a problem with the media, so what could be causing such awful burns?

From that picture I can’t see an awful burn, just a burn with a slow-down zone around 1 to 2 G point; if you are sure that is not the media to blame perhaps something else caused a slow rate transfer on the IDE channel your burner is attached.

My TY media does better in my 716 and 3500s, 3550/4550.

109/110/1640 like the cheap CMC E-01 +R and MC004.
