I recently upgraded from Winamp 2.91 to Winamp 5, and now I see it has a fairly large collection of streaming videos ("Internet TV") that you can watch. One of these streams is constantly showing a anime series that I wouldn't mind having a copy of.

Trouble is I don't know how I would go about capturing them. Like the title says, they are NSV format. Is there any software or methods that will allow me to easily save the streams to my HD?
