For example, in data being streamed (but not stored) on your system it is possible (but not easy) to capture the IP packets and then reconstruct the data. Of course you need to know the protocol being used and how to reassemble the packets. Then, even if you do that, the data may have been compressed so you would have to know what compression algorithm was used to uncompress it (not so hard). And the data may have been encrypted with the receiving application being responsible for decryption. So, you need to know how to decrypt (not so easy). That said, I gave you a start for saving those movie clips. I also can tell you the key to saving BBC videos is probably an application called iplayer or get_iplayer. And it isn't all that amazing at all. This has been happening for a long, long time. Have you ever used vncviewer, run a remote X session? And think of the simple case of "sftp user somehost". There you have a data stream between 2 systems...with no easy way to capture the data stream and reconstruct it.
