Pioneer 205 glued sessions to compare (higher speed - lower jitter :-):

Pioneer S12JX (a positive correlation - jitter/LDC with speed):

We appreciate you sharing that information. Are the LDC/BIS results comparable from all three drives for the same MIDs?

Your point about OPC off giving better results is also true most of the time. There are a few drive/MID exceptions, but you're generally better off leaving OPC set to off/no.

I'm not arguing, I was just surprised that ASUS/LG writes with better jitter

Your CMCMAGBA5 and MILLENMR1 tests look excellent, Quintam. :spoko:

Coopervid is correct. Jitter does not seem to affect the readability of a Blu-ray disc. This is also my conclusion after burning and testing several thousand Blu-ray discs. The far more relevant and useful tests are LDC/BIS and a read test (TRT).

Yes I remember thank you.
I also found this recommendation:

I never noticed read failures based on jitter. Only based on LDC / BIS. We had some discussions about critical LDC / BIS values on a PM base in the other forum.

YES, but without OPC I received constantly lower LDC|BIS.
as about LG, recently I checked also a jitter and was surprised ASUS 16 FW3.11 on 4x has better jitter with CMCMAGBA5 than 2 my Pioneers at any speed
based on my table for CMCMAGBA5:
ASUS16 4x - Jitter avg 9,1%
Pio205 6x -10,1% (at lower speed jitter is higher for example for 2x -12,2%), but LDC|BIS are better at 2x
PioS12 2x - 9,6% (at higher speed jitter is higher)

Discs w/o layer break (25GB) are usually a no brainer for any BD drive. Even using a LG drive.

I've recently recorded about 100 discs with this MID code on 2 Pioneers.
it seems for me OPC better to switch off and all quality options in Pioneer utility also off.
