Which Progressive Panasonic DVD players have the RP-56 de-interlacer and the zoom/shrink function of the RP-91 for use when playing non-anamorphic DVD's on 16:9? (or is it called Letter Box Zooming Shift?) What is the 4:3 TV Zoom function? I thought there were new Panasonic single and 5 disc players that had the de-interlacer of the RP-56 and the non-anamorphic zoom/squeeze function of the RP-91. Yes? No?
