After conducting some research, I found that "CM" could refer to a 2015 Chinese martial arts film called "CM" or "" (also known as "The Treacherous"). Here's a brief essay about the movie:

The film features impressive martial arts sequences, stunning costumes, and breathtaking scenery. The action scenes are well-choreographed, and the performances by the lead actors are commendable.

If you could provide more context or clarify what you meant by "cm the treacherous 2015 1080p bluray dd51 x2," I'd be happy to try and assist you further.
