One example to answer the question: I'm a computer science student in the biggest university in my city (the 3rd biggest capital of brazil). And guess what? Until recently (at least 1 year ago), I was the only one with a DVD burner (the Digital Image Processing Lab bought a dvd burner 4 months after me and my best friend just bought one). 3 burners in an universe of 1500+ people gives an idea on how hard would it be to burn that media ....
The prices dropped fast recently, at least in the US. I bought an external USB2 burner maybe two years ago, for $400, and now an internal drive can be had for about $70, and a USB2 enclosure for maybe another $50. Has Brazil seen any of that drop?
