Problem with my component feed to monitor
 

Last week with my A1 connected to my Dell 2407 via component video cable, the video played back full screen beautifully. I shot some air to air video over the weekend and now the video will not play on screen. I cross checked the monitor with a composite connection and it plays full screen. Also, the tape plays fine over my Samsung 1080i big screen. I've checked my connections and settings. Anyone have a suggestion for a solution. I'm hooked up to a MacBook Pro.
