Don't know if this has been posted before, but there are a couple of stream options available for Centre Court.
Eurosport, Windows Media
, just go sign up for an account and verify via email. When a match is live, just click the red "video" button.
Note: Bwin not work with Firefox. Use IE or Safari.
Note: It works fine for U.S. people. You just can't bet.
Note: Bwin shows many of the European matches, so it's a good idea to sign up.
Note: Both streams generally kick up at 3pm GMT. For ES, look for French dudes in the draw.
Have fun. Play hard. Enjoy live tennis.
