For some movies freezes the screen while the sound continues to play. For other movies it will play just fine until the last 20 minutes (you know, right when you are on the edge of your seat?) and suddenly, there's no sound!! Then I have to completely close out of everything, and start the movie over again. The desktop shortcut doesn't always work so I usually have to open and shut my DVD drive in order for it to start the movie again. All in all, this is a very cheap program and I do not recommend downloading it.
