Avoid the 'Substance' DVD
The "studio" (which is in fact one guy in a cellar) merely took the standard bootleg floating online and added the downloadable subtitles (I wonder if he realizes that he needs the translator approval for that?), and released the horrible version as "an official" DVD.
The pirate was even too stupid to find the actual promotional Turkish poster for this film and use it for the cover - instead, he just pasted a blurry colorized snapshot from the bootleg as the cover image.
Avoid, even for free.
