What you may be seeing is the inherent judder that NTSC discs exhibit due to 3:2 pull-down.
Film is shot at 24fps. When PAL discs are made, they just speed it up slightly to match the 25fps of PAL video. When making NTSC discs, a process called 3:2 pull down is used where each frame of film is alternately put into 3 fields, then 2 fields etc to obtain the 30fps of NTSC.
This always creates a certain amount of judder.
It's possible that the deinterlacer could have an effect and make it worse. It would be a useful experiment to try an analogue interlaced connection and see what that is like. That way, the deinterlacer in the TV would be employed instead of the one in the DVD player.
