PUO

(synonyms: Prohibited User Operation)

A PUO on a DVD-Video Compilation is a Prohibited User Operation. It allows for a DVD compilation to have instructions set for navigation buttons on a DVD player remote for example. It can be used to prevent a user skipping past an anti-piracy commerical or FBI warning, or escaping from such content by using the Menu button. PUO is considered a form of DRM and is usually frowned upon by consumers.
