Have to agree. Recently calibrated my brother-in-law's home theater and his Denon AV receiver required us to use his front projector DLP to see all the OSD menus in order to calibrate the channels properly. His Denon is even more complex, it has the ability to calibrate each channel for each DSP mode it is in. I couldn't imagine doing all this on a one line display on his receiver. Also, many if not most DVD players these days require the same access to their menus via an OSD similar to my Oppo player.
