The other reason to run your video through your new receiver, whether you allow it to upscale or not, is that it overlays the GUI onto the display, which is extremely handy for all of the complicated setup options that the new crop of receivers have available. Just make sure when you're shopping, if this is important to you, that you confirm the GUI can be overlayed on all output resolutions and connection types. Even some of the newer receivers are limited in their ability to output the GUI over HDMI and at all resolutions.
