catch Posted June 15, 2011 Share Posted June 15, 2011 Hi, my question is about the layer break sector. I know the easy way is to let Imgburn to calculate the optimal but I want to use the “user specific” box and get the same result (I’m odd, I know). These are the files I want to burn (they are on my hard disc now so I can calculate the real size and I know which file is on each layer): Layer 0 (1.897.416 Sectors) VIDEO_TS.IFO 12 Kb VIDEO_TS.VOB 2,52 Mb VIDEO_TS.BUP 12 Kb VTS_01_0.IFO 94 Kb VTS_01_0.VOB 223 Mb VTS_01_1.VOB 1 Gb VTS_01_2.VOB 1 Gb VTS_01_3.VOB 1 Gb VTS_01_4.VOB 408 Mb Layer 1 (1.974.452 sectors) VTS_01_5.VOB 1 Gb VTS_01_6.VOB 1 Gb VTS_01_7.VOB 1 Gb VTS_01_8.VOB 1 Gb VTS_01_0.BUP 784 Mb The “real” layer break sector is 1. 897.416 For the same layer break point (and forgetting the padded sectors to make L0>=L1 and multiple of 16), Imgburn says that the layer break sector on the disc will be 1.897.700 284 sectors have been added (in this example, with other files, the number of sectors added are different), I guess these sectors are used for the file system specifications… My question is, If I want to use “user specific” layer break sector and get the same result, which one must I write on the box, the “real” one (1 897 416) or the other with the added sectors?

LIGHTNING UK! Posted June 15, 2011 Share Posted June 15, 2011 If you really want to do it manually, build a large single layer image (change the SL media size), examine the ISO (IsoBuster) to see where the VTS_01_5.VOB file ends up LBA wise and use that as the layer break position when you build it a 2nd time (having reverted the SL media size). Got to say though, it's a crazy thing to do! Just let the program provide you with the options and pick 'VTS_01_5.VOB' from the list. Your 'manual' thing is just a massive waste of time and effort.

catch Posted June 15, 2011 Author Share Posted June 15, 2011 (edited) Thank you Lightning UK, I know it's crazy, but this is the reason: I want to backup "Abyss". This dvd has multi-story (seamless branching). The layer break is in one cell that is interleaved. If you play version 2, you notice the pause for the layer break, but if you play version 1, there is no pause (someone said on this forum that this is the method is used on superbits dvds for seamless layer break, I think). The case is that imgburn don’t show this cell as an option, so I thought to do it manually… Version 1 (PGC 1) … Vob 41 (no interleaved cell) Vob 42 (no interleaved cell. SPLIP flag YES) Vob 43 (interleaved cell. SPLIP flag YES) … Version 2 (PGC 2) … Vob 41 (no interleaved cell) Vob 42 (no interleaved cell. SPLIP flag YES) Vob 44 (interleaved cell. SPLIP flag NO) … In the vob file (VTS_1_4.VOB), the cells go something like this: … Vob 41 Vob 42 Vob 43 Vob 43 Vob 43 ----------------------- LAYER BREAK Vob 44 Vob 44 Vob 43 Vob 44 Vob 43 Vob 44 … The only option Imgburn gives on this dvd is Vob ID 42 (on pgc 1 and pgc 2). With the layer break in vob id 44: L0 1.995.978 sectors L1 1.916.300 sectors I’m using version 2.5.1.0, why Imgburn doesn’t show that cell as an option? Thank you.

LIGHTNING UK! Posted June 15, 2011 Share Posted June 15, 2011 For starters, you should never ask for help with an old version of this program. It was decided way back when, that interleaved cells shouldn't be displayed as layer break options. Both ImgBurn and PgcEdit function in this way. If you haven't modified anything on the disc, using Read mode and Write mode would get you the exact layer break. Link to comment Share on other sites More sharing options...

If you haven't modified anything on the disc, using Read mode and Write mode would get you the exact layer break. I've just downloaded the latest version, sorry. If I do it your way (create image file first), I can't change things like UOP or delete warnings, and if I do it my way (files on hard drive), I can't get the original layer break because is in an interleaved cell, am I right? Well, I will think about the best option for me... Thank you very much. Link to comment Share on other sites More sharing options...
LIGHTNING UK! Posted June 17, 2011 Share Posted June 17, 2011 It might be too late now but I've added a 'Show Interleaved Cells' option in the settings that will enable you to position the LB where you want it via the GUI. You can see it in action here on my copy of 'The Abyss' (Special Edition - Disc 1). Link to comment Share on other sites More sharing options...
