Distorted/unstable picture

I recently bought a Panasonic TX-32LMD70 TV and a Panasonic DMR-EZ25EB.
When watching films via the Recorder or watching recorded films, there is an odd picture distortion. Parts of faces move separately as if there is a delay and scenery moves. It doesn’t appear to be a stable picture…
Films on the TV are ok. I have rechecked the connections and all is ok. I have a loft high gain TV aerial as I am only 16 miles from the transmitter on the Isle of Wight. I would appreciate any help or guIdance as to the cause and the remedy please !
