I purchased the Zenith DVB216 ... The image it provides is unstable. The image ocilates slowly from perfect to fuzzy color to black and white and back. The cycle is irregular. Sometimes the picture is perfect for as much as 6 minutes before running through the cycle. The worst part of the experience is dealing with Zenith's customer representatives. I called them immediately on discovering that the DVD was not working properly. They suggested trying a variety of things which I attempted. No change. My wife and I have called Zenith 5 times. We have repeatedly been lied to. We have never been able to locate the same service representative twice. Each service representative has promised us a variety of things, a new DVD is on the way, etc. At this writing I am almost 2 months into the process of obtaining a working DVD from Zenith. At this rate the technology will be obsolete before we obtain a working sample of this wonderful device. ...
