I have created "Ghost" files so I can include cover art in my library for movies I have purchased from VUDU. They are just text files renamed with a .vob extension. In media center, I associated .vob files with a batch script that launches a web browser, and points it to vudu. When I click on my files in theater view, MC just flickers and slows down without launching the files. I'm thinking the slow flicker might be because it thinks it should be changing my refresh rate but it doesn't even launch a web browser in the background like it should. When I navigate to the .vob file locations within MC and click on them, they work. In standard view under the video tab clicking on them does nothing.
