Martha is on DVD in Germany, and you can get it via amazon.de (don`t know if it has english subs, though.)
Ali: fear eats soul is available on a double DVD (with optional italian soundtrack!) and some bonus material (short film, documentary, discussion with director and actress, etc.), also in germany and via amazon.de. It is said to be an excellent release regarding picture quality and bonus material.
And the best is that the film has optional english subtitles, which is a rarity on german DVDs!
