One more question, probably easy to answer, but I haven't found it in a search yet:

Setting up a new config, drag DVD over to the WATCH page. Later, I want the BLU RAY button instead. If I go to image gallery and drag it over the DVD image, both remain. Delete the DVD and the device goes away???

Also, the Wii is in the image gallery but not the page setup, so same issue - drag something over in page setup and later bring the Wii logo over and I have two images.

Thanks for advising.
