retsam Posted January 20, 2010 Share Posted January 20, 2010 I tried to burn some ISOs but got that "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." error. So I extracted the files and rebuilt with ImgBurn selecting a layer break point. But the resulting iso is much larger than the original. The original was 6.64gb and the ImgBurn rebuilt iso is 7.62gb. I know the rebuilt iso will also fit on a DL but I'm just wondering the reason why or if I did anything wrong. Thanks for any info. Link to comment Share on other sites More sharing options...
LIGHTNING UK! Posted January 20, 2010 Share Posted January 20, 2010 It's to do with the amount of padding that was added due to the layer break you selected. Link to comment Share on other sites More sharing options...
