Decrypt local video

[infodimarino]

It's possible to decrypt a video stored on local\private network drive, without using tv ftp connection?

This becouse I recorded some video with Tv and stored them on NAS.

Thanks

I manually used tool "Extract all keys to CONTENTS..." from "TOOLS" menu so key file(with size >0 byte) was generated.
Then I used DeSTRoi - Decrypt Samsung TV Recordings using the key file generated and decrypt video.
Is there any method to generate the key file without copying all my videos on Tv HDD?
