movies folder as default

In the "movies' menu on Front Row displays movies from iTunes and then has the option to enter the Movies folder. Is there a way to change this, so that I get my movies from my movies folder all coming up in that movies menu, instead of the itunes videos? And the same thing with the TV shows menu (I have a TV shows folder in my home directory that contains all of my episodes), can I make that the default TV shows directory?

Also, is there a support article that shows what formats Front Row can support (video and audio)? Can it use the plugins that Quicktime can to support extra formats?

Thanks.
