I've tried twice (unsuccessfully) to make custom backgrounds following the steps in:

Steps 1-5 work fine, but I'm confused by step 6: "Once the iso making is done, open the image with a ISO Editor, such as UltraISO."

UltraIso can't open it. I can add the .PIM files I made, but when I burn the DVD it doesn't play in my AVIC-D2.

What am I doing wrong?

Just when iI think I've figured it out, I try to burn onto a DVD and find out there isn't enough space. I need 5.9GB and I only have 4.7GB. Gonna have to go buy some new DVD-R's with more capacity.

You'll need dual layer dvds or you'll have to delete some files. The tutorial tells you how to finle the files you need to delete to burn a single layer dvd.

Ok, so I got an 8.5GB dual layer DVD and burned everything. My AVIC-D2 doesn't read it.

What's going on? Can someone please help? Thanks.

Well, I finally got it to work. I added two images but only one works. I used Alcohol to burn the ISO on a dual layer DVD.
