Any plans on DVD rebuilder pro to support layer breaks?

[jamos]

When I create a ISO with rebuilder pro and then try to burn it with Imgburn I get a error saying layer break has not been set. Any plans on adding this functionality to rebuilder pro?

If you do a DL the same layer break point is used as in the original. The only time that is not true is if you force layer break removal.

Yes unfortunatly i am mastering a dvd from two double layer ones. I can use pgcedit to do this though.

well you need a properly mastered disk. this means 1 layer break in the right spot before it gets to rebuilder.

Yes true, but would it work after resize? Because you are downsizing the title hence the layer break would be in the wrong postion after the resize. My title is 11 gig. compressing down to 8.5gig. I am using PGCedit to set the layer break after I use dvdrebuilder to resize, it seems to work ok as long as I resize small enough around 96% of capacity of a full dvd-9.

I'll look at adding some code to adjust the layer break when outputing to DVD-9.

That would be awesome JD ]:->

I think with dual layer disks becoming more affordable (bout 1.50$ here in the states) this feature would be a excellent addition to dvd-rebuilderpro.

Follow up:

By reducing rebuilders sector size for a dual layer disk I was able to get pgcedit to pad and achieve a suitable layer break.

I set DLTargetSectors=4010480 in the rebuilder.ini which is about 97.15% of a dvd+r dual layer disk.

I was told around 95 to 96% total capacity is the ideal size for a dual layer disk to almost always get a correct layer break. Maybe the default for total sector size on a dual layer should be reduced some?

I am going to try DLTargetSectors=4006870 to see if I get more choices of where to put correct layer breaks (be around 96% of DVD+R DL capability). If that works well you may want to make the dl size this by default JD (if compression is used). Especially if your going to incorperate layer break logic in rebuilder pro.

I think it all depends upon the structure of the disc you're trying to author and on the size of the VOB/CELLs. Luckily when the software has as much control as DVD-RB over the process you can alway split a cell into two cells if necessary in order to make a layer break. One tough part is considering and applying ILVU properly, because it can't cross the layer. But anything can be done with enough effort...

...anything can be done with enough effort...You are a brave man to even CONSIDER taking this on, sir!

The thing about layer breaks--the proper or "best" place for one can be such a subjective thing depending on the program being "broken".

Regardless I know just enough about this to know that while I understand one can add cells to provide options for selecting a LB, this is not something I have taken on so I would welcome any options you might come-up with jdobbs.

True but the default of 98.7% of a full capacity DVD+R DL disk is really pushing a layer break possibility, unless you have split the dvd up into really small cells. (most I would say would like to use a existing chapter break). Maybe Rolz can work with you on this? His pgcedit works like what you are looking for I beleive (maybe make it a plugin?). He shows you a list of possible legal break positions, then once one is chosen he will then automatically pad the video_ts file to get layer breaks in the correct posistion if possible before he starts mkisofs.exe process. Probably could be done when a user hits the prepare button and has dual layer selected. It would be a lot of work to do I do not doubt.

For now PGCedit works fine to create the layer break after i rebuilt it with rebuilder as long as I set my DL target sectors small enough.

IF anyone else is having issues with remastering dual layer disks then resizing them down to a dvd-9 and not getting a correct layer break, this setting works really well for me in being able to set a correct chapter break after the rebuild is completed using PGCedit. I have tried this with 3 merged dual sided dvds and all produce suitable layer breaks at chapter breaks.

rebuilder.ini in [options]

DLTargetSectors=4006080


works well with movies with good size chapters. And you do not have to split cells. If you do get a cannot find suitable cell for layer break in PGCedit then reduce this number slightly (should be a multiple of 32 though).
