Wondering what I need to do to use the usb on this TV to play movies. This is what I would like to do. Use a portable hard drive and plug it into the usb port in TV to have all my movies on one hard drive and clean up the clutter with movies everywhere. I ripped one movie to a AVI format and TV couldn't find that file. So first of all is it even possible to do what I'm trying and if so what format do I need to rip DVDs to make this work?
