Just bought a 100 spindle of YUDENT02 (8x DVD+R), and am perplexed by its apparent lack of quality. This is T02 Rev 00, full-face printable, bought from SVP in the UK. Serial numbers are 5C532A104489PG (embossed in center ring) and TG001159 (printed in centre of dye).
Attached are images showing PI-PO scans of various burns at both 4x and 8x. As you can see, this 8x rated media is significantly worse than the 4x rated T01 Rev 01 at both speeds. I’m using a Plextor PX712A, f/w 1.05, master on IDE2, running in Ultra DMA mode. Burning with PLextools Pro v2.20. Any thoughts?
