I have a Mitsu HD and RCA DTC-100 and for some reason it has started showing a Vertical Blank Spot on the right that varies between about an inch and an inch and half. Anyone else having this error? If so how did you fix? As long as I use the HD output of the DTC-100 it does this intermittently. Sometimes when watching local HD and others when watching regular (local or DSS) channels.. I called RCA but they blamed it on the tv and said I needed to align the picture to the right BUT this does not seem right since if I change the RCA so its output is the S-Video it does not have this error. Weird!
