wireless headphone reception on 2006 Honda Odyssey

Just bought van. Can't seem to get consistent wireless headphone reception with dvd. Works fine with radio and cd, but chatters or nothing with the dvd. Have changed batteries and the dvd being played but nothing.

Did you ever find out what was causing the reception problems?
I have had the same problem for years and have never found a solution. Any ideas?
