Question 1

What is the difference between bdxl discs and m-discs ?

Accepted Answer

Ah, this is fairly straightforward:"BDXL" refers to the Blu-ray specification for quad layer, 100GB discs. You can read about that here: https://en.wikipedia.org/wiki/Blu-ray_Disc_recordable#Version_4.0.E2.80.94RE_4.0.E2.80.94.28BDXL.29"M-Disc" refers to the actual technology employed in the recording layer. In this case, M-Disc capable discs must be written by M-Disc capable writers, but instead of changing the color of the disc's dye, or changing its phase, these M-Discs and burners actually engrave the data into the disc in a series of pits and lands. M-Discs also come in all typical sizes; 4.7GB DVDs, 25GB, 50GB & 100GB Blu-day recordables. You can read about this here: https://en.wikipedia.org/wiki/M-DISC

Question 2

Just bought a blu-ray m-disc drive. will the burned m-disc be readable by a standard dvd drive/player? thanks

Accepted Answer

I just burned several BDXL 100gb's. They are marked with Blu-Ray logo and open read etc fine with the same Blu-Ray drive I burned with. Regular dvd drive does not see the disc. I am going to try a Blu-Ray only external drive - will update.

Question 3

Can someone recommend a drive that successfully burns the bdxl m-discs? my pioneer bdr-2209 is only successful about 2 out of 5 discs.

Accepted Answer

Yes. I've had excellent results on Mac OS X with the LG HL-DT-ST BD-RE  WH14NS40. I bought mine in an external USB3 enclosure from OWC, but I'm quite sure that any you find here would work just as well. I've had a 100% success rate with the 25GB discs.
