Total Noob ( Maybe this is a Sign)

So I know how to add textures, make buttons all the basics, at least I think… ,my noob question is how can I set the texture as a movie poster, or in a panel how do I set content to a play list with movies or media in general. and how do I play it.. is there a simple code I could see then I can build off of it I just cant figure out where to start.

Thanks for any help. and Happy New Year to all
