I have the same problem but i have found a separate part of the manual that says you have to use ones with a picture of earth and a 2 in the centre or picture of earth and ALL in the centre, (dvd-r vid mode, dvd-rw vid & vr mode). 
I haven't found them yet so can't say if they work. I am trying to copy vhs to dvd not sure whether that is vid mode or vid & vr mode. All a bit confusing, any hints would help.
