problem with Sony DVD - christy Moore uncovered

[cybmole]

I have a Sony dvd ( released a few years back ) Chrsty Moore uncovered which neither DVDfab nor DVd shrink can cope with.

here are the symptoms.

disc info shows 1 main title, 59 chapters run lengh 25+ hours! ( see screen - it's of the ISO backup but original DVD looks just the same)
all the vewable content is in chapters 1-39 & they all copy ok, i.e. I have every dong on the DVd including bonus & extra tracks if I just copy 1-39. But chapters 40-59 are used for navigation( I can see that by playing original dvd in Powerdvd with info toggled on ) , so leaving out those chapters casues menu selections to not work properly in the copy.

The wierd DVd length kicks in only if chapters 40 & later are included in dvdfab. If I exclude those then I see lenght of 1 hour 40 & can get a customised copy OK.

On a full copy, or on customised but with all chapters included, the copy process grinds to a halt around 80& complete. At first I thought this was read error & kept cleanign dvd & retrying, but no -it is not actually a read error jsut a slow down to zero at a set point ( = chapter 40 ? ) (& in DVDshrink an out-of-memory-error occurs when it hits the weird chapters. )

The entire DVD will copy perrfectly using DVDFab CLONE, so no issue with hardware reads ?

NB tried fab 6.18 with path player both forced off & forced ON - makes no difference.

DVDshrink also reports that original disc is NOT encrypted, so the only protection is from these weird chapters ?

SO onto questions:

1.if I burn the cloned ISO to a DL blank, will that play in both PC & DVD players without any further processing. ( Don't want to waste a DL finding you that it wont! ). I'm thinking that it should, as there's no encryption.

2. is this combination of" no encryption + weird chapter length" an old form of encryption, not much used & therefore not catered for in DVDfab ? (It is possible that chapter 40 is a slideshow & DVDFAB does not seem to like slideshows! )

UPDATE

I found a work-around solution - but do not understand how/why it worked

1. made an ISO using clone
2. made a DVD to DVD full disc copy (DVD9 - 100%), using the ISO on my HD as source.

creates a perfect copy (5.34 GB) , despite DVDfab stil reporting a length of 25 hours. All naviagation works on within HD copy so looks to be safe to burn.

any reason why this 2 step approach works, yet standard 1 step approach fails ?

Well have you tried this movie with pathplayer disabled? Also a cloned DVD should play just fine in your computer/DVD player but only way to find it is to burn it to the DL DVD as backing up DVDs is a trial and error process. Also have you tried to do the ISO you have saved already in the Copy FullDVD option to see if it can be compressed.

Edit: I see you already did try the ISO in FUllDVD mode as you posted while I was replying
