You can sum up Sony's 301-disc mega-changer design with two words: brilliant engineering. The DVP-CX870D and its less full-featured sibling, the DVP-CX860, are among the very few players that offer 2-sided DVD playback! Sony's center-mounted laser is the key. When a DVD reaches the end of side 1, just hit the "Flip" button on the front panel or remote. The DVD returns to its slot, the disc tray rotates 180º, and the DVD re-loads from the other side and continues playing! Built-in Dolby® Digital decoding lets you enjoy potent digital home theater sound with any 5.1-ready A/V receiver. The Disc ExplorerTM feature can display a list of every loaded CD and DVD on your TV screen (requires direct video input on TV). Details like a copper-plated chassis (for superior shielding), an anti-vibration top plate, and a heavy duty power cord all add up to outstanding audio and video performance. An awesome player!
