Review on Complemented Previously Documents Chronicles Documentary Staged by Mark Cai

The description says this movie will only work in a multi-disc player but doesn't explain what it is. I asked the seller for clarification but received no response. Of course, the disc would not play on any of my devices (Mac, PC, DVD player). Apparently you need a Polish DVD player. Don't buy this movie if you live in the US or just have a laptop to play it (my friend from Sweden stopped by last week and it won't play on her Mac bought in Stockholm).
