The answer is yes and no. The Xbox one has an app for playing optical media...DVD/Blu-ray...You will get the Cinavia warning if you play backed up Bluray or DVD. Xbox One also has released a separate media player for playing movies off an external HDD. Unlike the other app...This media player can play any Cinavia infected file, without triggering the Cinavia message. So Microsoft took the LG approach...detects Cinavia only on optical media. Not USB external hdd movies. Hope this clarifies things.
