If you're on cable and seeing both curtains and shutters on a widescreen image, , then you can use the different aspect ratio settings of the set to compensate for this (usually called "zoom"). While nearly all broadcasters did transition to digital transmission, that doesn't guarantee all content being broadcast is HD. For example if a stations commercial playback system does only 4:3 video, and a commercial is send to them widescreen, playback would have both shutters and curtains.
Comcast often has digital avaliable without using their box. Try connecting the cable directly and rescan for digital (QAM) cable and see what you get. Channel numbers may look funny though, but you'lll get the picture.
