The way to get maximum boom for your surround-sound buck is to buy a home-theater-in-a-box system. The 900-watt YAMAHA DVX-C770 ($550) is a nice marriage of superior sound and video flexibility. Its DVD player can upconvert standard discs to hi-def through an HDMI output and it also can play compressed DivX discs and video CDs. | If your system is simple, your remote should be, too. The UNIVERSAL REMOTE CONTROL URC-R7 ($40) has thousands of preprogrammed codes and includes an easy DVD setup guide. |
