I would have just asked this on your first thread, but then again, it is CloneDVD specific ... so ok then ...
Also do different burning programs handle layer breaks differently(in other words if i used clonecd to rip and it preserved the original layer break, then i used clonedvd to burn, would it mess the layer break up????
Yes, to answer your question, but "mess up" is the wrong term to use. The automatic (but unoriginal) layer break placed by CloneDVD works very well in most cases.
You have to change your thinking a little and decide something. Do you want to make an exact 1:1 backup of the original disk (nothing removed) or do you want to copy movie only. The two different programs (CloneDVD and CloneCD) are designed for two different purposes. If you want 1:1 with the original layer break, you can't remove any title-sets or tracks from the original (which is the purpose of a non-transcoder like CloneCD). Also, since CloneDVD is a trancoder, by it's very nature it is has to choose it's own placement of the layer break even if nothing is removed. Can't change that, that's what transcoders do.
So, having established that using a transcoder program that allows for the removal of anything (even if you didn't), it requires that a shift in the layer break be made, I suggest that if you are making a DL backup, you might as well use a non-transcoder, like CloneCD, to make a 1:1 mirror because space is not an issue with DL. I.E., you are not compressing onto a single layer media so you don't need to remove anything to get the best quality of 100% non-compression.
If you don't want to watch the extras or play foriegn soundtracks etc included on a 1:1 CloneCD backup then just don't watch them. But if you want a mirror of the originals layer break, you have to use CloneCD (or other non-transcoder software).
BTW: AnyDVD features can be set to allow you to bypass "Annoying Adverts" or bypass "warning screens" etc when you play your backup made 1:1 with CloneCD. This feature of AnyDVD definately allows you to use the >>| chaper jump button to bypass anything and get to the menu. Originals don't let you jump past the stupid stuff (it's a user prohibited "feature" of originals).
Having just mentioned menus, I'll also suggest that if you decide to use CloneDVD because you want the movie only on DL, be sure you include the menus ("Preserve Menus" selection). Your automatic CloneDVD layer breaks should work fine on most backups. But If you don't include the menu's, you may find out your backup's default audio and subtitle tracks don't work. Some DVD's are authored so the tracks are matrixed through the Menu structure. Just a little warning to save you making a second, working backup.
Also, use only Vervatim DL+R media and booktype/bitset it.
Give this thread a read-through.
