The Pirates of the Carribean warning worked because the movie was still in the theatres at the time. If you are making a vid for a movie that has been out for some time, I don't think any spoiler warnings are necessary. And yes, we do have programs, and yes, you can write your own blurb. My suggestion would be to put "contains spoilers" in your vid blurb in the program. I (personally) think spoiler warnings for something that's already rentable (or aired this past season or what-have-you) are unnecessary.
