Possibly a language conversion is a problem here. Please read the instructions again and follow them to the letter. The Nero Infotool report is a text report of you system and it is saved by clicking the diskette button beside the drive list. Instruction 2 said to use a 4x DVD+RW. Instruction 3 said to reset the EEPROM learn; did you do this. Instruction 4 said to do a Nero quality test. You did not read the thread link in my post, as your Nero scan attachment is still in JPEG format and not PNG format.
Create data disc is the last option in the Run Test menu. The quality test is the 4th option in the Extra menu.
I don't like the look of all those extra little dips in the burn scan. This indicates buffer underruns. Is your system busy doing something else during the burn? Is your system very slow (what CPU)?
Erase error! Was this using CG5G and the Erase Disc option in Nero CD-DVD Speed?
