The Samsung HT-Z320T can improve the look and sound of virtually any DVD. An HDMI connection up-converts DVDs to near 1080p, so they'll look great on your HDTV. Auto Sound Calibration (ASC) balances speaker output for optimal 5.1-channel surround sound reproduction, and front / center speaker cones with bio kelp fibers deliver clearer sound with less distortion. And, you can enjoy stored music and media using the iPod dock with video, audio and iPhone support.
