I checked through the last few weeks of postings, and don't see much detail about the burning process, though it seems to be a bit unconventional...

I downloaded the NTSC DVD-9 from Usenet, and the NFO file says that ImgBurn is included in the RAR (it's not), and to specifically to use this program to burn the disc. I downloaded the latest version of ImgBurn (2.4.1.0) to do the job. When I tried to burn the ISO file, I got the following message:

"Optimal L1 Data Zone Start LBA: None Found! (VTS_51)
This image has not been mastered correctly for burning onto a double layer (OTP Track Path) disc.
None of the cells meet the 'DVD-Video specification' criteria for a potential layer break position.
Do you want to continue anyway?"

I said yes, and it started to burn. I was never prompted with a checkbox about the layer break as the NFO describes. The thing burned all the way through with no error messages, but the result was a coaster which is not even recognizable in the drive. Can anyone shed any light?
