Hi I'm wondering if anyone know a method to check a DVD that has been copied to hard-drive. I'm playing of my movies from the Hard Drive, and I have a couple of times experienced that the movies may not be playable. The issue I have is that the player (Vista Media Center) starts to load the title, shows a black screen and never gets to the main menu. I assume this might be because I have the "Remove irritating commercial and trailers" box checked. However, I DO want to remove that shit. So, is there any program that may batch process all movies on a hard-drive to verify that they are OK and seems to be fully playable?
