It looks like electrical interference from an outside source, the fact that two sets do the same thing seems to confirm that, possibly the DVD player itself or something in your home.
The Electrohome may just be able to reject it better.
You used to see this type of interference back in the days of rooftop antennas when a car with a leaky plug wire would drive by.
Try another DVD Player, if that doesn't work start unplugging devices like Wall Warts and Computers.
