Basically all non-LTH BDs. The way I've understood it, the big selling point in M-Disc DVDs vs. regular DVDs was the inorganic dye used in it. But if you buy a non-LTH BD, you'll have an inorganic dye anyways.
The company that actually made M-Discs also went bust and there's a lot of conflicting information on the Internet whether or not the current M-Discs are real M-Discs or not.
