I need help locating a movie...(dubbed)?

I need help. I'm trying to locate a movie which is German/Czech. I know it has been dubbed in English, because I used to love it when I was younger, and it was in English. It's called 'Schneewittchen und das Geheimnis der Zwerge' which is basically 'Snow White and the Seven Dwarfs'. Can anyone tell me where I can get/watch this movie from where it is dubbed in English? I'd really appreciate it! Thanks x
