From the menu screen, go up until the 'Doctor Who' logo is highighted. Press Play to see the full length title sequence (with complete two minute theme).

Then, go Right. A Cyberman symbol will appear over the photos next to the logo. Go left and the photo of Patrick Troughton will be highlighted in green. Press Play and the disk will jump to a re-mastered version of the famous 'Family' scene in episode 3 (voted as one of the best ever Doctor Who moments - OK, I'm a geek).

There is also a third egg - anyone know what it is?
