detecting layer break removal

[wallbert]

i haven't burnt any dl dvds before, but i am familiar with basic authoring and most of the programming infrastructure. a while back i had made an iso image of one my discs that was getting those ugly discolorations on the underside of the foil. i tried to watch it again the other day, and most of is unreadable - so i'm quite happy i got it in time. but the problem is, i don't remember what processing i did to it... i used dvd decrypter to get the files, but i'm not sure what i used to make the iso (it wasn't dvddec). to make matters worse, i was interested in DL burning, so i wanted to mess around with it and remove/move the layer break and so on, but i have no idea what iteration of that i got to, or if i kept the copy i messed with. in any case i now need to burn it, so before i pop out any expensive coasters i'm wondering: how i can figure out if the layer break is still there, if it is, if it's the one from the original disc, and if not, if i can tell if the break was removed properly.
help! :o

Hi!

You might want to read the postings about the capabilities of PGCEdit and IMGBurn...

(Considering your initial concern about the original's deterioration, it's rather surprising that you didn't INITIALLY store away an unmanipulated .ISO image file)

i figured pgcedit would be what i needed to use, but i still need to know what to look for regarding the break. i guess i should have asked how much it would matter if it was improperly removed - i just don't want there to be any glitches at the original breakpoint in addition to a pause at the new one.
as for backing it up, i've lost at least 3 hard drives in the past two years (due to physical failure, not absent-mindedness ;) ) so i consider myself lucky i still have a copy at all.

If you burn your DVD with PgcEdit, you will be prompted for the location of the layer break. If the original seamless flag is still clear, there is a good chance that the original cell will be automatically selected by default.
Anyway, the exact location of the layer break doesn't matter too much. You can select another cell if you wish, as far as it is in the legal range, and PgcEdit will not let you select an illegal cell.

ok, good to know. in preparation of burning it i've been reading up on the dl problems, including that some software will "butcher the image by improperly removing the layer break" or something to that effect, and that's what i was worried about since i'm not sure what program converted it to image. but if it will still play over the old point regardless then i'll just pick a new one and hope for the best. thanks for your inputs.
