Best is to study the demo scenes and read the documentation. In general you do the following: 1. create a material with a texture slot (allmost all shaders that come with Unity have this). 2. Make a MPMP instance in your scene. 3. Add the material you made to the videoMaterial slot of the MPMP instance. 3. Add a mesh to your scene and use the material you created for the mesh renderer of the mesh. With these steps the video texture will be injected into the material and all meshes that use this material have the video texture as surface when you run your scene and a video is playing.
