Dual layer DVD9

]I have just tried a dual layer burn for the first time results were slow at 2 times using Pioneer 109 burner, What is the correct way to do the burns? I tried direct using Nero but the region protection came up I went through DVD shrink which encompasses region free,I burned the DVd via “shrink” ignoring the 4.7gig warning and continued to get a 100% burn which would been 45% on 4.7gig the results are very good resolution Can I use Nero direct to burn And of course which version carries region free?
