Not to be a
techhead, but this could also refer to the
underground practice of capturing
streaming video or
audio that was not meant to be captured. Typically this is done by inserting a
hacked mixer or
sound driver into the
OS.
For example, one could accomplish this feat on Realaudio/Realmedia (.rm) streams, icecast streams, streaming mpegs, or quicktime streams. (not to mention stickin' it to the DVD CCA by h4X0ring your DVD video after it has been decrypted...)
