I own both for use in a NAS media server (not player).
The black is the best all-round performing 7200RPM 1TB drive currently available. I read a test report that it is almost as fast as the WD Raptor 15000RPM drives. I use it for the system drive. I'm not 100% sure what the report said about heat, but I seem to recall that it ran reasonably cool. It has more noise and it is more expensive than the green. However, it has a 5 year warranty. Heat and noise aren't an issue for a server.
The green is cheaper, quieter, cooler and uses less power. It's not as fast as the black, but it holds its own with most other 1TB drives. I use the green as my backup drive. As I add drives to the server, I will use the green drives to store media.
Streamers don't need speed and you are limited by the USB interface anyway. Low noise, power, and heat are good to have. Go with the green. 8MB cache will be good enough.
