I have many LaserDiscs titles that are not available on DVD or BluRay as well as 35mm and 16mm prints in my library.  Is there away to customize Profiler so I can add these two additional categories to the MEDIA list?

There's a small problem with new media types.  In order to select the new type you must first click on the right-most block in the Media type block.  The displayed title may not be the Media type you want.  But entering the name of the type you've added will display a drop down menu of the added media types.
