Question Need a way for a Verbatim Blu-ray disc on a LG Blu-ray writer (WH16NS40) to write at maximum speed of 16x ?

The LG 16x Blu-ray writer WH16NS40 I bought a couple of years ago use firmware version 1.03. For a couple of years, I use single-layer data blu-ray discs writing at a slow 8x speed. I recently bought a 50-pack of Verbatim single-layer 25GB Blu-ray discs that can write at up to 16x, and it's the only brand in the market that can write 16x blu-ray discs. I use Cyberlink Power2Go11 to write data to DVDs and Blu-rays.

However, when I inserted that new writable blu-ray, the program will only allow up to 12x maximum speed, not 16x!! What gives in to the restriction? Do I need a different type of software to make writing at least 16x possible, or the worst case scenario is to roll back the firmware one version to make 16x blu-ray writing possible (along with 4K movie viewing compatibility)? I really don't want to roll back the firmware as it's difficult to do so and it needs to be done in Windows 7 32-bit OS.

Did the old firmware work at 16x speeds? Does not sound like you ever used that speed, so thinking the firmware change can do it is a bit faulty.

Other software, sure that may help, Nero is good but can be expensive.

Could also be an issue of those disks.

Really I would stick with the slower speed, over the years I have learned that the faster the media is written the more chances there are of errors during play back. Last time I burned disks I was using 4x speeds pretty much 100% of the time to maintain good compatibility when playing them back.

I'm pretty sure ImgBurn will do it ... freeware but very good. Just be sure to manually set the speed ... don't use AWS (automatic write speed). My experience has also been that slower burned discs are more reliable but ... give it a go and let us know!

Well using ImgBurn, this is what the device info said, despite supporting a max read and write speed of a single-layer BD-R at 12x. I could try forcing a 16x speed, but I don't think the hardware will allow it.

I use cdburnerxp, im able to force burns at different speeds only did it once, but it was at a lower speed. might be worth trying. but dont do a bunch like that, do one and test the disc out and make sure the burn was good/data is fine, and if all si well then do all of them like that.

Have you tried forcing a 16x burn? I'm curious as to the result.
I tried forcing burning 12x on an older 8x BR-disc using IMGBurn, the hardware won't allow it as it sticks to 8x burning. For 16x, I don't think it's possible unless I roll back the firmware one version below for that hardware.
