I've authored a DVD in Encore, then used PGCEdit to change the layer break, and set it to burn with ImgBurn after creating the ISO. ImgBurn, however, pops up an error, saying that the 'User specified layer break position exceeds L0 capacity'.
If I close ImgBurn, then reopen and attempt to burn the ISO that way, it says:
---------------------------
ImgBurn
---------------------------
Optimal L1 Data Zone Start LBA: None Found! (VTS_01)
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?
---------------------------
Yes No
---------------------------
I get the same result if I author an ISO straight from Encore, then try to burn that with ImgBurn.
What on earth is going on?
