Streaming video is independent of whether or not the content was stored
and then streamed to you or if it is a live feed and then streamed to
you. It's streamed in both cases. In fact, to protect their content,
many sites incorporate a streaming server trying to thwart would-be
thieves from stealing their content. They could provide it as a file
(to play in your web browser or download it) but instead proffer that
file a few kbytes at a time by streaming it.
You obviously don't understand why or what is streaming media sent over
a network. Streamed media does NOT have to be just for live content.
Any file can be delivered via a streaming server. You have never
noticed that the streaming video has the same content when you visit
seconds, minutes, or hours later?
Whether ESPN is showing a live feed or a stored video file (replay),
streaming video is used for both. If it's a continual live feed (it
never ends), just how do you think you will capture it all? It's
neverending. Every capture program will just continue to capture more
and more bytes with the captured traffic generating an ever increasing
file. Since the replays come from a file, there is limited content and
eventually all the bytes sent to you get captured into a local file. Of
course, if the replay (file) is 2 hours long then it's going to take you
that long to record it. Actually it seems to take less time for me to
use capture software to grab the stream than to view the stream but a
2-hour movie (replay) is still going to take a long time to capture and
I wasn't interest in anything ESPN has to see how long it took.

Some capture software captures all streams (there can be more than one).
For example, when at hulu.com and capturing a movie, you may end up
capturing the advertisement streams along with the movie stream. They
interrupt the movie stream with the ad streams; however, the capture
software should capture each stream and you will end up with a movie
file without any ads. Hulu is one of those that use RTMPE (RTMP with
encryption) that the commercial capture programs refuse to capture (they
wrongly claim it's a DRM scheme when, in fact, is isn't without a
security token being involved). StreamTransport will capture hulu
movies (i.e., it will capture RTMPE streamed media) but it is a clumsy
program and forces you to use Internet Explorer's libraries.
