I have the same problem! Exactly the same model. I thought these external harddrives were plug-and-play into the usb ports of new lcd tvs - the HD is configured for use with my macbook and works fine on it, but my files wont show up on the tv at all. Someone told me it had to do with NTFS and that I need to install Fat32, but that it limits you to transferring files smaller than 2Gb which sounds pretty crap and I really have no idea what it all means and exactly what I need to do. Ugh.
