MD, try this on your box....

First, you have to do the advanced set up on the 8300, specifying all the resolutions that the SXRD can handle (which are all of them). Then, you have to go into the 'second settings' menu to enable pass through (i.e., hit settings button twice to be taken to the advanced settings screen (not sure that is the name but you get there by hitting the settings button twice; first is only a quick settings screen)). Set to pass through. Then make sure the 8300 isn't "zooming" the picture either...every now and then my kids must hit the wrong buttons on the remote and cause this to happen, making the picture noticeably off (i actually watched a whole movie one night, gremlins, thinking they just did a lousy job on the source, but in reality the 8300 was zooming the picture )
