I've looked at an installation with WinXP Pro SP2, NERO 6.6 and a Pioneer DVR-A06 (DVD-106) with hacked 1.07 and 1.08 firmwares.

For some reason, NERO stopped working correctly when writing "no-multisession" data DVD+Rs; the problem is in 6.6.0.8 and 6.6.0.12 and perhaps also in 6.6.0.6; uninstalling, using the clean tools, and re-installing 6.6.0.3 solves the problem so it isn't the media nor a bad firmware.

The problem is that somehow the track doesn't get closed; diagnostic tools indicate a closing problem (the track isn't closed hence the session can't be closed hence the disc can't be finalized).

6.6.0.8 and 6.6.0.12 both write DVD+RW correctly, even writing a DVD+RW and then using the same compilation on a DVD+R causes the problem.

6.6.0.12 works absolutely brilliantly on a LG burner, it's just an issue with regression testing on the Pioneer.

I therefore voted "Poor".
