Sony DRU-500A problems

[nonicknamesleft]

I started using the latest Nero 5.10.15a with firmware 2.0E , once I burn .nrg image to hard drive using image recorder and then burn image back to dvd using sony recorder it works fine at 2 X using Clone dvd-r purple base......but I must do as two separate jobs in Nero?

If I burn to image hd as temp image and then to dvd all in one job i get coasters.
Strange but at least its working.

Cheers
Scott.
