The Da Vinci Code BD -- PIP function question??

[Factionparadox]

HI

please forgive me if this is a silly question but iam new to Blu-Ray. I recently bought a Sony BDP S300 player and it works brilliantly however i have a question.

On The Da Vinci Code DVD one of the special features on disc 1 is `unlocking the code picture in picture` feature. My question is how do i do this?. I have clicked on the special features on disc 1 and there is no picture in picture function only a select scene commentary

thanks for any help
