An IXB disk image file is a proprietary file used exclusively by the Ulead DVD MovieFactory software. It is essentially a full rip of a DVD file that has been placed on your computer's hard drive but is unlike other such image files in that only the Ulead software can burn it back onto a blank DVD. Fortunately, it is not a difficult task to accomplish.
Launch Ulead DVD Moviefactory.
Insert a blank DVD into your computer's DVD-R/RW drive.
Select the "Copy Disc" option in the MovieFactory window, and then click "Next."
Enter the desired name for this DVD into the appropriate text box, and then click the "Browse" button under the "Copy Disc From" section and navigate to where the IXB file is located on your hard drive.
Select the IXB file and click "OK."
Select the DVD drive containing your blank DVD as the "Destination" drive, and then click "Output." Click "Yes" if you are prompted to erase any data on the disk. Ulead DVD MovieFactory will now burn the IXB image file to the blank DVD.
