The Free Agent Theater product provides 1080i output and connects to the TV using component, s-video, or xxx outputs. The interface is similar to your computer -- just browse the files on the removeable hard drive till you find the directory you want to use, and press the play button on the remote.
For those relatives that don't know much about technology, you can record family movies and photos to the drive from a PC, and then just send them the drive to plug into the theater unit.
The product also includes a docking station for your computer, so that you can copy data files over using a USB connection. It reads standard DVD movie formats as well as other video formats.
Also, while the display is only 1080i, if you have larger images, you can zoom in and with each zoom level, the picture reloads, so you will see the highest resolution possible.
