Hi,
A few days ago i burned a DVD+R DL disc that makes problems. I authored with DVD-Lab Pro and burned with Nero. I used a Ricoh DVD+R DL 2,4x and have a LG 4163B as burner.
The disc plays fine on the computer but on the standalone its not that simple. If I just jump forward from chapter to chapter, it works. But if I start from a former chapter and wait til the layer break comes, the standalone hangs a bit and then jumps 10 minutes ahead (to the next chapter).
Before the burn I checked with DVD-Lab Pro that there is a chapter point within the layer break range. And I thought that Nero will do the rest automatically. But I suppose that was false and Nero didn't set the layer break correctly. So I will do the next DL burn with pcgedit+dvddecrypter which is said to be a good combination. Right?
But...I have another problem with that disc that confuses me a bit. The menu hangs too.
First a few more details about my compilation:
There are two movies on the disc. The first one is the bigger one, so it's spread over the two layers. The movies have the same resolution (720x576) but different aspect ratio and different audio streams. The first one is 4:3 and the second one 16:9. So I used two VTS. The menus have different aspect ratios, too. The VGM menu is in 16:9, the VTS1 menus in 4:3 and the VTS2 menus again in 16:9 - so that the menus have the same ratios as the movies. There shouldn't be a problem with that, should it?
But as I said, the menu hangs too on the standalone. When I select the first movie from within the vmg menu, the vts1 root menu should appear. But the graphics and the background stays the same. The only thing I see from the vts1 menus are the highlight frames. It's a bit difficult to navigate... :D
The first guess is that this is because of the incorrect layer break. Well, I made a test (single layer) DVD+RW with a comparable menu structure and that one worked flawlessly on the standalone.
I just wanted to ask here: There should be no problem at all with such an aspect ratio mix (provided the layer break is correct)...right? I just want to be sure, because I don't want to produce anymore DL coasters. The discs are expensive enough.
It's of course the most logical assumption that the layer break is the cause for the problem with the menus. But I just don't get it... What exactly is the root of the problem?
I'm no expert in dvd structure. But I thought that for one movie, the IFO comes first. Then the VOBs are written consecutively, and after the VOBs comes the BUP. So with my compilation only the BUP of the first movie should be on the second layer... So the layer break shouldn't be problematic for the vmg menu/vts1 menu change. Or am I getting things here totally wrong?
