I just purchased a Visio e552vl yesterday. When I try to use the DVD player now some of my DVDs won't play correctly. Some still work, but others do not. The DVDs worked fine on my old TV connection. Now the DVDs will play full audio, but the video flashes on and off every second. One second you can see the picture, next second the screen is black, next second it is back on and this scenario continues for the duration of the movie. Is there something I can adjust on the TV to make this video issue stop when using my DVD player?
