Hi! I have found a strange difference between Verbatim DVD+R 8X (MCC003) in jewel case and Verbatim DVD+R 8X (MCC003) in 10pcs cakebox.
The media from jewel cases written at 12X all give the same results when scanning. When the speed reaches 9X and higher, the PIE/PIFs are going up to unacceptable values (1st scan).
When writing at 8X, it is OK, but you can see how the disc spinning slowed down on the scan (the PIE values go down) (2nd scan).
The media from cakebox are perfect. They can be written at 12X with no problems. (3rd scan).
The strange thing is, that I thought that media in jewelcases are of higher quality than those from cakeboxes… but this proves me wrong.
