Today i burned my first Panasonic 4X BD-R 25GB , purchased trough ebay from seller jp-buy.
MID : MEI-T02-001
I burned them at 4X , in my Pioneer BDR-206 1.05 FW (Ebay china version)
I burned them at 4X , in my LiteOn iHBS-112-04 FW PY06
I Burned them at 4X , in my Asus BW-16D1HT FW 1.01
I must say, This is the best quality scans i have ever been able to achieve here.
Just for fun i tested some of my older 2x BDR-DL 50GB discs with Panasonic MID that i burned in 2009 , they were still very good scans even after 4 years! Better quality then some of my pressed original discs (regarding to AVG LDC / BIS atleast)
Also , i found this analysis of blu-ray media degradation,
Where Panasonic (MEI-T02-001) had the longest durability.
I have included my Scans , all burned in 4x , and read in 4x.
(I Will post one more post later on , with scans burned at higher speeds like 6x 8x and 10x) Just takes forever to scan at 4x CAV.
