¿Can the PIONEER BD-RW BDR-209D read TRIPLE LAYER M-DISC or normal BD TL disc?

[deadoralive45]

I have a BLU-RAY PIONEER BD-RW BDR-209DBK drive with the 1.51 FIRMWARE version

The PIONEER drive does not recognize my blank or recorded 100 GB triple layer M-DISCs, while my ASUS BW-16D1HT reads and writes 100 GB triple layer M-DISCs on the same PC ¿Even if it does not write M-DISC TL (100 GB) should it be able to read them if it is a BD-XL drive?
I haven't tried with normal BD TL because I don't have one, but the pioneer drive does read and write normal 25 GB BD's.

My main question is if the drive can read TRIPLE-layer M-DISC discs (100 GB), and another question is if it can read regular bd TRIPLE-layer discs (100 GB).

In the firmware notes it mentions triple layer support in firmware 1.50.

This instruction manual also refers to the triple layer, but only associates it with writing, not reading.

This pdf alludes to a low version of the firmware where the TL read function was removed.

The M-DISC website states that it only records M-DISC single layer (25 GB) and DL (50 GB).

Also say that the website has been out of date for some time and that firmware 1.50 is from 2018.

 

 

While IMGBURN says it does not read or write BD-XL, only single layer (25GB) and dual layer (50GB) blu-ray, which is what the M-DISC website says.

 

Thanks!

That last screenshot says it all.  BD-R XL and BD-RE XL read and write are not supported.  So, reading TL and QL media is not possible on this drive/firmware and writing isn't supported either.

Right But why is TL mentioned on some official pioneer sites with this model? Is there any way by modifying the firmware to extend the ability to read TL? I've seen on forums like makemkv where they flash the drives and in some cases you can make UHD to read TL.

From what you posted from the change log history of the firmware TL/QL support for reading and writing was available and one point but removed at a later point.  Whether it was ever restored or not is up for debate, but it seems unlikely they would restore something after taking it away.  And the most likely reason the TL and QL support was removed was so that no one would even DARE to think about copying a 4K Blu-Ray.

I opened a post in the makemkv forum and they told me that maybe I could get that with my pioneer drive, but they ask me 25 dollars for a remote flasher, it's something strange really.

I have seen that there are public firmwares of bluray recorders like ASUS or LG that modify to read movie bluray discs or even improve increase the capabilities of the device being able to write or read faster, or read and write TL UHD's but I dare not, I would dare more if there was a public pioneer 209dbk custom firmware to the access of more people, as it is an entry point to attacks on my computer.

 

Plus $25 is 1/4 of what my pioneer 209dbk cost and I doubt it has a warranty in case I break it or something, I will wait to see if one day they make the firmware public.
