He set the break just fine, see where it says in the log
Setting it manually in imgburn will not overcome these two problems:
1 - it is a really old disk drive (they were made back in 2004/2005 if what I'm googling is correct)
2 - RITEK-S04 are relatively new and still a somewhat uncommon media code (Ritek's are just plain crappy disks to begin with, though S04 is an improvement over D01)
The problem is, your drive doesn't support that media/type of disk. Either get a new burner, or hope there is a firmware update for yours that does support that media code (highly doubful), or get disks that yours can support (ritek D01 or verbatim/mkm 001.) The errors imgburn is giving you should be rather clear that the drive does not support writing any data sectors on that type of disk... though it looks like it did the lead in/out ok (meaning that disk was probably coastered.)
thanks corey1492 for your input. i actually had the same "invalid address for write" error even using verbatim (made in singapore) discs. you are correct about the drive being old and i've already updated to the latest firmware after the first coaster. it didn't make any difference though.
you've also confirmed my suspicion that manually setting the layer break or loading a .dvd file with layer break info doesn't change anything, lucky i didn't have time to try this yet or another coaster for me.
in addition to my drive, i've also tested it on my brothers laptop which contains another older lg supermulti drive (but different model) with the exact same error.
this weekend i will try burning my backup image at a friends house and see if i can get a good burn. then hopefully i will find the culprit, whether i got a bad batch of discs or my lg burner.
on a side note i've searched on google and found at least one other person with the same burner as me successfully burning 360 backup image OK.
