I believe that in Law theft is defined as:
The dishonest appropriation of another's property with the intent to deprive him or her of it permanently.
Thus (in)appropriately flicking a few TV buttons which results in the TV just happening to allow you to view some 'gentlemans relish' and, as the owners have not been deprived of it permanentlty, would suggest (using my simplistic logic) that it ain't theft !
However if there is a theft, it's more than likely being commited by the hotel who are charging (on a vast scale) for viewing films and (more than likely) not passing on the royalties to the film producers !
