I've been communicating with them and it looks promising. Here is the description of what it does:
"Embedding unique digital user DNA into each video copy.
Every time your customer downloads or streams a film, Xvid AutoGraph automatically embeds a unique customer ID tag as digital DNA into the delivered video. Each copy can then always be traced back to its original recipient revealing any illegal uploader with pin-point accuracy. Digital DNA, integrated on the fly."
Comments on this greatly appreciated before i dive into it with test integration.
