Burning Dual Layer Discs

I think I put my post in the wrong section before, see here:

Please reply as I have no idea how to burn DL discs!!

Have a look here for the easiest way.

In respect of setting your own layer break, look at the guide on the PgcEdit site. You first need to set up PgcEdit's burn function (Options - Input/Output - Burn/ISO Creation settings)

OK - I get this error message.

"Error: Cannot find the first VMG Sector"

What does that mean? I opened the DVD in PgcEdit like normal. Also, Nero will burn DL discs, should I automatically rule that out or not? If it sets a default layer break, will that be bad?

drfsupercenter: Sounds like an authoring issue. What did you author it in?

I run mine through DVD Shrink, then to PgcEdit, with no issues at all.

And yes. Nero may well reset the LB. blutach may tell you this. Heh

Also: Imgburn is the new *burning only* version of DVDDecrypter. The newest PgcEdit works with it well, and easily.

@Pinan - If PgcEdit offers no choice whatsoever for the LB then you have authored the disk with cells of too big a size, so that no cell boundary falls within the LB parameters. This is bad but not irretreivable.

Find the middle of the title and split a cell with DVD Remake Pro - guide (see my sig for DVDRMP site).

If only one is offered (it will be the original and be blue), take that one!

This means that VIDEO_TS.IFO (and BUP) is probably not present or corrupt. The first VMG sector is defined in this file.

No, the dark blue line in my guide is simply Windows XP's highlight. There should be some cells though.

DVD Shrink has no place in DL copies. But if you do use it, make sure remove LB is not checked in preferences (unless of course you want to use PgcEdit or ImgBurn to set the LB manually).

As I said before, the key is that a cell boundary must exist near the edge of the disk. Are you sure you have the burning setup done right?

Hmmm... I used TMPGEnc DVD Author and then replaced all the VOB's and IFO's (Except for VIDEO_TS) with the ones from Nero Recode. As suggested in some guide. Should I just burn with Nero, or should I not use a default LB.

[blutach]

You can't do that drf. VIDEO_TS contains important info about all the titlesets. Do not burn.

What you can do is import them properly.

From PgcEdit: File - New DVD. Then import the titlesets. Click under VMG, First Play. File - Import VTST titles. Navigate to the folder which contains your titlesets. Pick an IFO for a VTS which contains your VOBs (VTS_01_0.IFO for example). Select move VOBs. Do this for as many titlesets as you need.

Import Menus (including VMGM with Menu - Import Menu) following the same method).

Author the commands for VMG First Play. Check there are no bad jumps with Info - Find Jumps to Nowhere. Trace through your DVD to ensure it plays.

But it might be easier simply to go back to what you had in TDA.

Now, I get this message.

"Can't find a suitable cell for the layer break!"

Why is this? There are four titles on the DVD, wouldn't the break occur between the second and third movies? What should I do now - it won't continue with this error message.

[blutach]

The LB follows very defined rules. Layer 0 (the first layer) MUST have more data in it than L1. And of course, both must have less than the absolute limit. And a LB can only happen on a cell boundary.

If your DVD is authored so that it can't find a cell that meets these rules, PgcEdit will hollder like it just did and not permit you to create an ISO (and make a coaster).

Therefore, you need to calculate where your cells are and probably split the cells of one of the titles - DVD Remake Pro is the easiest tool for this.

Please post your IFOs and I can tell you where things are awry.

[drfsupercenter]

What happens if I split a title? Will that mean that the movie will be split in two? Will I still be able to select that title from the main menu and it will play all the way through? Also, DVD Remake Pro is not free! Is there a free way to do this?

As for the IFO's, I will post them later, for I am on a school computer now.

[blutach]

All titles on commercial movies are currently split. But they play seamlessly, so you don't notice the various cells (except at the layer break, where there is a slight pause).

To do this for free, try TMPGEnc. DVD Author - trialware for 30 days.

I have DVD Author. However, how does that work with the Nero Recode way? That way you use DVD Author to make the menus, and then overwrite the normal VOB files with Nero Recode ones to retain the subtitles. If I use DVD Author, the subtitles will be gone! Also, why wouldn't the break just happen between movies 2 and 3? Theoretically it would work because the combined time for movies 1-2 is about 3 hours and the time for movies 3-4 is only 2.5 thus there would be more data on the first layer. Is there another program that forces the layer break to occur there? And what does Nero do? It WILL burn DL discs, does it just make some default LB?

Here are the IFO files for you.
