Build Mode - and General Question

[BoSox2882]

I was wondering this. Is it possible to build an ISO (or burn from) from the VIDEO_TS file of the file in the DVD Drive? What I mean is, while in build mode, can you hit browse, go to my computer, drive D (or whatever), select the movie, and then the VIDEO_TS file?

 

Wouldn't that also give the original layer break as well. In the one I tried (I didn't create the ISO, wasn't sure what would happen) it gave me the original layer break as an option. This should result in the same way as 'read' mode, but would give the option of using "seamless" playback.

 

Also, just a general question. Does ImgBurn, and for that matter other burning programs, add dummy sectors to the end? I used build mode to make an ISO, then opened it in write mode. It had added 6 sectors to the end from the original. Or is this just postering, and will they be same once burnt?

Read mode makes an ISO from an unencrypted DVD. It preserves the LB.

That doesn't make a lot of sense to me I'm afraid.

 

Build mode should tell you exactly how big the image is that it'll create. That size should then be the same when you open it in Write mode.

 

Can you provide a test case when that's not true?

The last ISO I built, when I open it in write mode, it says the sectors are: 4,149,984. When I open the original in read mode, it says the sectors are: 4,149,978.

The size of the ISO built by ImgBurn doesn't have to be the same as the one made by another program.

 

So if when you say 'original' you're talking about a disc that wasn't created and burnt by ImgBurn, that's why.
