You have several issues you need to resolve, some of which may be just that
you didn't correctly copy the code into your post. Your issues are:

1) You're mixing two means of activating your object in your client code.
You should either register the well known object (either via the config file
or thru code) OR you should use the Activator.GetObject() -- there's no need
to do both. So, to use the activator (which is my preference), change the
code to:

IPlayer player = (IPlayer)Activator.GetObject(typeof(IPlayer),
"http://localhost:80/Test/MyServer.rem");

Note that you have to provide the full URL in the call to GetObject() -- you
had omitted the "MyServer.rem".

2) Your MyRemote() object only has a parameterized constructor. In order to
be used as a server-activated object, it must have a zero-argument
constructor.

3) The DLLs should be in a subdirectory of your web app named "bin".

4) You've specified a binary formatter on the client side but not on the
server side.
