this really does work.  I just set it up and it even works with
mlb.com.  Completely uninstall Real Player or RealOne.  Once it is
uninstalled go to your Program Files folder and delete the real folder so
it is completely gone.  Restart your system.  Then download this file from
the following link
http://shaohao.vip.sina.com/RealCodecs11.zip
This is about a 7.5MB file so be patient.  Once the download is finished
unzip the file and run the executable.  This will install every possible
plugin that realOne uses.  Then simply install the Tara plugin for Winamp
which can be downloaded right from the W4TB site.  Yes, I know this isn't
the latest version of Tara, but I have found bugs in the latest one so I
don't use that one.  Once you have both programs installed simply go into
winamp, hit control+p for preferences, F for file types, then tab over to
the select button and press the spacebar, then tab back over to the close
button and press space on that and you are done.  This is absolutely
awesome.  I can listen to mlb games now without that bloated annoying
RealOne player on my system.
