My video jumps all around as others. I think I was the first to complain of such an issue way back in the day. Anything played through the concertone unit gets fubared - even Netflix played off my iPhone. Played through the tv is fine. I have been trying to get this fixed since I first bought the trailer in September 2011. Bob sent me the video interface - aka a little electrical dudad that plays midle man between the tv and the DVD player. I have just installed the video interface and my issue remains. I would very much like to get this resolved. I have taken my trailer to two dealers, installed 3 new concertone units, installed the video interface, talked, emailed, and worked on this for many many hours. I'm tired, and I need this fixed now. Please help... Anyone...
