It was suggested that I try a pass thru, so I connected a second VCR in series with the source machine. The resulting display on Easy VHS to DVD plus was the same, some 'rippling' at the top of the video image.
I am working on digitizing the family archive of VHS tapes using Easy VHS to DVD plus (just bought). Like Bobby333 I am also getting an annoying ripple at the top of the video. This distortion does not appear on the TV when playing the same tape on the same VHS machine & cable.
A 3 second sample is in the attached clip, as generated by Roxio Easy VHS to DVD plus.
