I've been using mega changers for my CD collection for some time now. Been thinking of doing the same thing for my DVD's. I have Sony mega changes, 400 disk and a 200 disk, that are controlled by a computer via CDJ and Slink-e. I’ve been researching both the Sony (300 disks) and Kenwood (400 disk) DVD changers. Are these my only options? 480P is required, computer control is a plus.
