Just purchased the Deneon. I have component video as inputs from cable box and DVD. Component video out to HiDef monitor component video in. Cable video works fine (HiDef video displays correctly), but the DVD video does not. Widescreen (16:9)format does not fill the screen (as it did when directly connected via component cables directly to monitor). Any ideas why the monitor is not treating the DVD video coming thru the AVR correctly?
