I'm not familiar with the HD Fury, so I went to their site. Based on what I see here , this device will do you absolutely no good in dealing with the issue of getting composite video to a secondary display. For that matter, nothing will work if the source component is unable to output both component and composite at the same time. That's where the problem lies, I think. If your DVR will output at 480i from the composite at the same time it's doing 1080i from component (which it should be able to, as plenty of other devices do - including my HD DVR cable box and every OPPO player I've used), then we have some options to work with that don't require an HD Fury in the mix. If using the component output shuts down the composite output, then I don't know of a device that will achieve what you are trying for.
