108 D Problem with DVD+R?

Pioneer 108 D
Firmware 1.14
Nero 6.0.0.11

I have problem with writing Prime Disc DvD+R.
Everything is like normal, until I try to read that disc.
It simply doesn’t recognise it.

In nero, when I select “continue multi.”, I can see all filles already written, but when I click on “finalise dvd”, at burnig process, there is error with “Close-This-Disk-At-Once” procedure.

This is only + media that I can buy.
So is this problem with my 108D or something elese?
