HR54-700 Genie will not output 480i over component (YPbPr) connection. - DirecTV

I wanted to switch from using a composite to component signal to remove dot crawl distortion, but I ran into a problem.

The manual for Genie DVRs lists 480i as an available resolution for component video, but our CRT television will only display a distorted double image for an instant before displaying the message "NO SIGNAL." The double image would indicate a 480p signal being output instead.

The Genie is set to only output 480i, so that is not the problem. Could it be a bug?
