Make Movies from my External Hard Drive Show in Front Row

How do I make all the movies stored on my external hard drive appear in front row, right now I have it set up so that there is an alias in my movies folder which links to my external hard drive and when the hard drive isn't connected the alias doesn't show in front row and it does when the external is plugged in which is all good, but what I want to know is can I somehow make it so that the external hard drive movies are added to the list of the movies on the internal hard drive without having to click on an alias folder to get to more movies. Can it be done?

Thanks
