I have been previously using a Gigabyte motherboard (845G) with my PX755A and Nero 22.214.171.124 and DVDs and CDs all burn perfectly.
Recently I upgraded to an ASROCK 775i65PE (865PE) motherboard with Pentium D 930 and 1GB RAM. I use Nero 126.96.36.199 with Windows XP Professional. I have also upgraded to the latest 1.05 firmware.
In Nero, CDs and DVD-Rs still burn perfectly. But attempting to burn a 16x DVD+R (TDK) generated a Power Calibration Error. Testing to create data disc using Nero CD-DVD Speed with DVD+R also generated a Power Calibration Area Error.
However, when I use the same DVD+R disc in PlexTools Professional 2.35 for the Write Transfer Test, the test completed successfully. Although I have not tried it yet, it seems probable that using PlexTools Professional to burn a DVD+R would work, but for some unknown reason Nero does not work with DVD+R anymore.
I have tested with the 1.02, 1.04 firmware also and all generated the same Power Calibration Error with Nero when using DVD+R and no problems with CD-R and DVD-R.
Given that Nero worked perfectly with my last motherboard, I do not know what happened now that Nero no longer works when burning DVD+R (while still works with DVD-R and CD-R). Originally I suspected it may be a problem with my PX755A but now it does not seem to me to be the case since PlexTools Professional appears to work.
Please can anyone offer me some insight on this problem?
