Anyway I've come across IDFA TV and you can actually watch documetaries online. It's a Vimeo channel embedded in the page
Here is the link
I watched On the Street by Sérgio Bloch (57 min) and it was time well spent. It's about how different characters managed to make a living out of their performances on the street of Rio de Janeiro. There are visual portraits of the performances, including a disabled man and a prostitute but what makes it even more interesting is that it shows the richness of street life in Brasil. The creativity of the people and the economic interaction that is taking place is something that hints at the vibrant development of the country and present the urban setting in a completely different fashion than the fictional film Tropa de Elite, a successful film that has become a sequel with Tropa de Elite 2 now showing in Europe.
