I have a problem with my pioneer dvd-r 7000; when I played my dvd or when I try to record my dvd by compsite or components on the colour TV the image is ok, but when I try to see it on informatic monitor or in professional Tv monitor with “under scan” option activated I can see on the image a one discontinuous white line on the upper side of the monitor , I would like that this discontinuous line to be removed I don’t know if there is someone with this problem too but if there’s someone that can help I’ll be so grateful. Thanks
