How to copy videos, live video streams, or live news reports
(like from CNN) to your Windows computer

1. What you will need:
   a) The VideoCacheView app from NirSoft.  Here's a link:
        http://www.nirsoft.net/utils/video_cache_view.html
        Near the bottom of the page, there's a link to
        download the app.

   b) Another useful app is MediaInfo, which is able to
        determine the format of a video file.
        A link to it is:
        https://mediaarea.net/en/MediaInfo/Download/Windows

   c) Another app is the VideoSolo Free Video Converter, which
        can convert FLV format video files to MP4 format video files.  
        Here's a link:
        https://www.videosolo.com/free-video-converter/

2. Copying a video using the Firefox browser:
   a) Play the entire video or live video stream until the end.  
        Then close the browser.

   b) Run VideoCacheView.exe, and locate your video.  You can  
        recognize it by the browser you used (in this case Firefox),
        the very recent date and time, and probably its large file
        size.  Also, note the format under "Content Type".  

   c) Make a copy of the file on your computer desktop and change
        its file name to an appropriate name.  (If you want to post
        it on YouTube, give it a very unique name so you will be
        able to find it easily.  (Note: YouTube allows you to slow
        down the speaking rate of speaker without changing the pitch
        of his or her voice — a very nice feature.))

   d) If the file's Content Type is MP4, add the extension ".mp4"
        to the filename and you're done.  If the Content Type is
        MP2T, the file is an flv format file.  In that case, add the
        extension ".flv" to the filename and run the VideoSolo app
        to convert the file to the MP4 format.  (Also see Appendix 2,
        below.)

   e) Post the video on YouTube if you'd like.

Appendix 1
   The default size of Firefox's cache buffer for temporary files
   is 50 MB (megabytes) The cache is where Firefox stores all of
   its temporary files, including video files.  If you want to
   copy videos that are longer than, say, 10 minutes, you'll
   need to increase the size of the cache (so the cache will have
   plenty of room for all the files it needs to temporarily store).  
   Here's how to do it with the Firefox browser:
   a) Enter "about:config" (without the quotes) into the address
        bar (where "http://" URLs go).  

   b) After you "accept the risk", Firefox's internal settings will
        be displayed, and starting at the top left will be a search
        window.  Enter "browser.cache.disk" (without the quotes) into
        the search window and press Enter.

   c) Then right click on "browser.cache.disk.capacity" and click on
        "Modify" and enter the value you wish.  The units are in
         kilobytes (KB).  So, for example, 50000 is fifty megabytes (MB).

   d) On the next line, if necessary, modify the value of
        "browser.cache.disk.enable" to "true".  Exit the window and
        you're done.  

Appendix 2
Often a video will be composed of a sequence of several MP2T (flv)
files, and to get the complete video, this sequence of MP2T fles must
be strung together, from earliest to latest.  To do this, first
download and install the Avidemux app.  Here's a link to the download:

http://fixounet.free.fr/avidemux/download.html

Then, do the following steps:
   a) Use Video Cache View to find the video you want.  Then copy the
        MP2T files in the sequence to a folder you've created (They'll be
        very close together in time, spaced just a few seconds apart.).  
        Rename the files with names that indicate their order in time,
        and tack onto each the extension ".flv".

   b) Bring up the Avidemux app, and drag the files in the folder, in
        time sequence, into the area next to the column of option
        selections on the left. (Note: the first file will create an
        image in this area — just copy the succeeding files onto the
        top of the image.)  Make sure that a little window saying
        "Checking if timestamp…" pops up when you drag an MP2T file
        onto the area.  If it doesn't, the file hasn't actually been
        copied.  In that case, drag the file again.

   c) Under "Output Format", select the option "MP4 Muxer".  Then click
        on the save icon (looks like a floppy disk) in the toolbar at the
        top of the window.  Give the file a name and click on "Save".  
        The output MP4 file will be saved in the folder you created for
        the MP2T files.  Exit Avidemux and you're done.
