I need to make sure the story is in Portuguese since Zeca is Brazilian. Wait, the query is in English, but the story should probably be in Portuguese. The user might be looking for a story that can be presented in Portuguese. Also, including some historical context about Zeca and Gafieira would add depth. Maybe mention his career highlights, how Gafieira came to be associated with his music, and the role of samba in Brazilian culture.

I need to structure the story with an engaging introduction, background information, details about the DVD, the digital download process, and a conclusion about the impact. Also, ensure that technical terms are explained in a way that's accessible to readers who might not be familiar with Brazilian music subgenres.

I should also think about the DVD's content. What does it include? Probably live performances, behind-the-scenes footage, interviews, maybe some classic hits and new songs. The new download aspect suggests it's a digital release, so discussing the transition from physical media to online platforms could be a point. How does this affect fans' accessibility?
