I've recently bought three TDK DVD+R DL disks. They are labeled CMC MAGD02 media.
I burned an image at 6x with this result:
After this jawdropping experience, I tried burning at 2.4x:
Much better, but that layer changing zone is still problematic.
I then started a discussion with my CD/DVD provider about this media he sold to me and he insisted that the burning process is responsible of this performance. But I'm pretty sure my system works fine and the burning process was ok. I used ImgBurn 22.214.171.124 with a Lite-On LH-20A1S SATA burner (fw 9L09).
So... Is it the media, the burner, the computer or any combination of those three?
