I have managed to confirm by various sources that there will be no cinavia on video files.
keep in mind this is for videos files only on USB or DATA-DVD discs. I have not confirmed this for Blu-ray or DVD format. (DVD-Video)
It's interesting to know the Xbox One media player will be similar
to the Windows 8 video player built into metro. Will the Playstation 4 have Cinavia...? A company like Sony
who forced it into blu-ray AACS. And are pretty much the culprits who brought it to us in 2009 on the PS3...
I would say yes.
