Removing the Apple logo from iDVD menu screens

Inside the iDVD folder you'll find a folder named "Resources." Inside this one, open the folder called "Interface Files." Inside, you'll see some files named Parts1 through 10. These files are standard Photoshop documents, except with different Type and Creator codes. To open these files in Photoshop, check "Show all (file) types" and select "Photoshop" as file format in the "Open (as)" dialogue.

In particular, open "Parts4." The layer which contains the watermark is titled "name:watermark type:Tile." There seems no way to complete remove this layer or its content. If you do so, iDVD doesn't start up anymore. Instead, you have two alternatives:

If you want to remove the logo, you have to first clean the layer (just erase its content, don't delete the layer itself) and then make 1 almost completely transparent pixel anywhere within the canvas. Don't try to use the layer transparency slider. This has no effect within iDVD. As I said you have to draw 1 Pixel almost transparent.

Or you can create you own logo. All colors are allowed, you're not limited to grayscale nor are you limited in size. You can place the logo anywhere on the canvas, iDVD will automatically locate the center (or the lowest most right pixel?) and place it in the lower right corner.

In either case, save the file when you are done. Don't worry that Photoshop changes the icon and Type/Creator. iDVD won't care. When you start iDVD the next time, you'll see the result.

By the way, all other files named "Parts..." in the "Interface Files" folder are Photoshop documents too. Almost each and every GUI and DVD element of iDVD is stored within these files. If you browse through them, the button shapes (rounded rectangle, splash, heart etc.), button states, overlays and so on will show up. If you carefully study them, you will figure out, how to create your very own DVD menu buttons in iDVD.
