Fordman, Quite right, you don't need to do the grab5m thing now. That truncated address calculation could have meant ANY file got changed (rather than the bup). It might not have even been a file at all, it could have been something in the filesystem. I'd love to see an original disc where the layerbreak isn't on a sector divisible by 16! Not that I've ever really been paying that much attention but I have to say this is highly unlikely.

It doesn't keep it, it re-finds it. PgcEdit passes it via a CLI command parameter now. If PgcEdit doesn't physically call up ImgBurn to do the burning (i.e. you load ImgBurn manually), it's ImgBurn's internal IFO parsing code that's finding the layerbreak (as indeed it should do).

If you have anydvd/dvd43/dvd region + css free installed, please ensure they're disabled before you verify anything.
