Question:

How can I delete titles from within My Movies for Windows Media Center?

Answer:

My Movies have an optional "actions" page, which can be enabled and disabled in the configuration in Collection Management - open "Tools", "Options", "Media Center Interface", and make sure the "Allow user to access the action page" is checked. Now, on the movie details page in Windows Media Center, you can click up to navigate between the sub-pages, and navigate to the "actions" page in the end of the page list. On this "actions" page, you will find a delete option.
