From the developer:
iDVD1to3 is an AppleScript applet designed to help you modify the system attributes of version 1 themes included with version 3 of iDVD. It will probably work only if your installation of iDVD 3 is unmodified. You should be able to access the iDVD 1 themes for use in your iDVD 3 projects.
You may want to check out more software for Mac, such as Dragon FliX, CD/DVD Label Maker or Easy DVD Creator, which might be similar to iDVD1to3.
