I4U News reviews the TVisto HDTV Video hard-drive enclosure from MacPower and TyTech.

One use is to store all your favorite DVDs on the TVisto hard-drive in ISO format. The DVD movies can be watched in the same quality and with all features from the TVisto. On a 500GB hard-drive you could store about 80 full length DVD movies. The TVisto plays back video with up to 1920x1080i resolution, so you can use it with your HDTV and loose no quality here as well.
