Just another thumbs up for imgburn. I used to burn 80MT discs with DVD Decrypter, and it appears that the write functions of these two tools are identical.
I tried burning the image with a different utility and it verified ok, but gave me a "Reading error" in my AVIC-D3. Burned another copy with imgburn and this one came out just fine. The bottom burned portions of the discs even looked different, like the other software messed up one of the tracks somehow. Never knew software could have such a profound effect on burning an image. The burn and verification takes about an hour per disc
