Nero CD/DVD Speed, +R write test simulated?

In nero burning rom 6.0, i cannot simulate a write on a +R media, only -R (on +R option is disabled).

but in CD/DVD speed, you send write tests (show how the drive write on +r media, p-clv etc…
how is it done? does CD/DVD speed program support simulation of write on +R?

Using Nero, can’t simulate burning on a DVD+r either, only on DVD-R.
The pictures you see in this forum using CDSpeed to view the write behaviour of are created by using the “create data disk” in CDSpeed : this way the data is actually written to disk (no simulation).
Using my Plextor 712 with Plextool however, I can sumulate burning on DVD+r.
