Pixelation when Cloning UHD disks

[DrEvil2024]

Hello all, I have been cloning UHD disks for a couple of years and have around 130 backups.

The issue is that when playing most of my copies, I have occasional pixelation of the image. On average a handful of moments per movie, but it does vary. The image pixelates for a moment, just like when you have a momentary read error in a traditional disk player. No errors reported by DVDFAB during the Cloning process.

Notes:
These images did not give errors when cloning.
I play the ISO's in a Zidoo Z9X Pro player. (im sure its not the player as the pixelation always occurs in the same place on a given image, but if i re-rip that image, the pixelation appears at a different point)
I have 4 drives, all give the same issue WH16NS60, BC-12D2HT, BW-16D1HT, BU40N
I don't have the issue with BluRays, just UHD.
I update DVDFAB when a new update is available, so its been this way since I started ripping UHD's in Aug 2023.
System is windows 11, just replaced the video card RTX 4060

what brand of blank UHD discs do you use ??
perhaps try a different brand of UHD discs.

Hello October,
Thank you for the reply.

I don't clone to UHD discs/media, I clone to ISO files. The zidoo player has the ability to play ISO images.

Thank you for posting. Please find one of the original movie discs with this playback problem, use the latest version of DVDFab UHD Copy - Clone mode to make a new ISO copy and check the results.

Hello there,

with version 13.0.2.9 I tried 4 original disks

Star Trek - First Contact and Star Trek - Generations seemed ok.
Star Trek - Insurrection and Star Trek Nemesis both had minor pixelation but no errors reported during the process.

I see 13.0.3.0 is now available. if you would like me to try that it may take a few days to get some discs and review the results. i no longer have the disks above.
