Britannia Video on Demand

Could someone explain to me what the Video on Demand is on Britannia please? Are these pay per view movies or complimentary or both?

There are free to view movies, some that that you pay for and a selection of TV shows that are free to view.

One thing that might be important is several of the films have an R rating, equivalent to a UK 18 so if travelling with anyone younger that might accidentally stumble across them make sure you turn on the parental locks in the settings menu.

Thank you Hatters Cruiser, we are new to P&O. We are travelling with kids so I will turn on the parental locks, thanks for the warning.
