I'm assuming you're viewing on a 16:9 screen? If so, I can only suggest that if every other channel (including C4 +1) displays 'scope movies correctly (that's to say, letterboxed within the 16:9 frame), then there MUST be a fault with your DVR.
I can only ask: Are you
absolutely certain all your equipment is set to '16:9' (or 'full' or the nearest equivalent)?
