I have bought a new burner after reading the review from cdfreaks.com.
It`s the Samsung SH-203B wich came along with Nero essentials 7.
I have some problems with the Nero CDSpeed software. The start buttons for disk quality and create a disk were not working.
I used the search function on this great forum and I solved the disk quality problem by modifying the registry. But the start button for create a disk still remains grey. I tried CD Speed 4773 and 4775.
(sorry for my bad english)
