Please note that no movies are downloaded, only the MetaData is being downloaded. The new look and feel makes things much easier.
Use the "i" on your remote controller to get movie information.
Be warned it can take a very long time to download and build the MetaData files BUT once you have done it once things will be much faster.
All new OpenView products will have these MetaData files already installed and built.
