At the beginning of this video, we need to type the following into the command prompt: "rvm use 1.9.3". However, when I hit Enter, I get the following message in the Command Prompt:
'rvm' is not recognized as an internal or external command, operable program or batch file.
This is being done on a Windows PC. I had no problems doing this on a Mac. Is there a step that I am missing?

Both the rvm and 0.0.0.0 only apply if you are working on a OS X or Linux.
On windows the way to start rails is to type rails s webbrick will then tell you the address it's starting on. By default you can access the rails web server webbrick on 127.0.0.1:3000.
Use CTRL-C you will stop the webbrick server.

Try RubyInstaller.

4,557 PointsI have used the rails installer, and have verified that ruby and ruby on rails has been installed.
I skipped the "rvm" command, and typed in the two commands to create the treebook directory and to make a "rails new treebook".
When I type in "rails s" or "rails server", I get the following:
c:\CalNext\treebook>rails s => Booting WEBrick => Rails 3.2.13 application starting in development on http://0.0.0.0:3000 => Call with -d to detach => Ctrl-C to shutdown server [2013-04-29 12:39:03] INFO WEBrick 1.3.1 [2013-04-29 12:39:03] INFO ruby 1.9.3 (2013-02-22) [i386-mingw32] [2013-04-29 12:39:03] INFO WEBrick::HTTPServer#start: pid=4668 port=3000
When I type in the address given, I get a page that is titled "Network Error", and get the following message:
Network Error (tcp_error)
A communication error occurred: "" The Web Server may be down, too busy, or experiencing other problems preventing it from responding to requests. You may wish to try again at a later time.
For assistance, contact your network support team.
When I type ctrl+c to shut down the server, I get the following question that I don't see appearing in the videos:
Exiting Terminate batch job (Y/N)?
I've hit both "Yes" and "No". The server just won't come up!

39,199 PointsPaul Dietrich - There are a few minor differences between OS X and Window, learning about them is all part of the joy of learning to program 
Like I said before, don't use the address http://0.0.0.0:3000 instead use http://127.0.0.1:3000 on Windows.
If it ask you to Terminate batch job just answer Y as that's the expected behavior on Windows. If you want to know more about this behavior, check this out it's the first link on Google.
