[Info about +R DL from mediachance]

Hi,

Recently I've read info from mediachance.com:

_http://www.mediachance.com/dvdlab/Helppro/layerbreak.htm

 

+R DL is already pre-formatted as OTP where each layer must have the same amount of data. A DVD+R DL was not created for any extensive using of custom Layer Break and it is expected that the data will be equally divided (the layer break will be in the middle of disc).

 

It is possible to also set a custom LB for DVD+R DL, but this require that a writing application must:

* Honor the set Layer Break (not all recording application do)

* Reallocate sectors so the LB meet the DVD specification criteria

* Make the both DL layers equal by writing padding data.

 

What the hell ?

Is a lot of my +R DL, burned with not 50/50-layers, incorrect ?

 

Thanks.

Thanks !

Say me, please, your lucky LB-sector at least for common understanding.

Thanks, I'm going for +

 

But my friend has a lot of -R(DL). He has bought it some time ago for his writing standalone. Now he want to burn it on PC for DVD-Video. My English is bad, but his English is zero and he want of my help.

 

I want to understand, what I must to do with Scenarist's project for good burning -R(DL) by ImgBurn. As I understood, -R(DL) has predetermined LB on the edge of the media. I'll be very much appreciated, if anybody say me of the sectors range, where this LB is predetermined.

 

Thanks a lot!

Hi All !

 

Sorry, is anybody know answer on my questions ?

I can to buy of the Verbatim -R(DL) at low price but now I'm not sure - buy it or no ?

[Unable to find any cells that could be used for the layer break (part2)]

-R DL dont work for dvd films as you can't set the layer break

Have I right understood that LB-point is predetermined on the edge of the -R(DL)-media and can't be changed ?

Must whole L0 be filled to the edge of disk in this case ?

Can any length gaps be inserted on the -R DL ?

 

Thanks!

[Dual Layer.. again]

Oooh! (He is sighing of relief)

 

Thanks a lot!

[Dual Layer.. again]

Thanks!

 

I was afraid, when I've read your:

"That info was based on an older version of ImgBurn that didn't support reading the layer break position from the .DVD file."

I've thought, you plan to remove this options in the new version.

[Dual Layer.. again]

Now I've looked once again in the guides section:(sorry for retelling)

 

How to burn an image with ImgBurn

 

1. Load ImgBurn

2. Switch to 'Write' mode (Click the 'Mode' menu at the top and select 'Write').

3. Insert blank CD/DVD (depending on image size!)

4. Select a file to write by clicking on the 'Browse for file' button.

5. Click the big 'Write' button.

6. Wait a while zzzzz.....

Finished!

 

As I've understood, ImgBurn suggests a LB-options in the 'Build mode' only.

 

Thanks.

[Dual Layer.. again]

The layer break options in the settings should be left on 'calculate optimal' - regardless of what he/she has read elsewhere! That info was based on an older version of ImgBurn that didn't support reading the layer break position from the .DVD file.

Sorry for maybe silly question, is that means, the layer break options in the settings should be left on 'calculate optimal' always ?

Even through I'll burn ISO image (DVD-Video) without .mds ?

Where in this case will be layer break ?

 

Thanks.

[Where is my Layer Break sector ?]

Probably my bad English don't allows me to describe clearly my thoughts :-(

 

Yes, this time, when my LB-question has occurred, I burned VIDEO_TS folder, which was created by Scenarist. Yes, this time I burned in ImgBurn's 'Build mode' and I've don't changed setting in ImgBurn back on 'Calculate Optimal'.

I've understood, that my 'user specified' value overrides value, which I've selected from layer break dialog in ImgBurn's Build mode.

I know, that LB sector is a phisical place on the disk, where laser is refocussed to 2-nd layer.

I understand, that logical sector of the LB-cell is predetermined in the image and burning sofware must to refocus a laser to 2-nd layer in the exactly determined place.

I've understood very well my mistake.

 

But until ImgBurn v2.1.0.0 was released, I often burned ISO images, has been created by Scenarist. I burned this images by DVDDecrypter's 'ISO>Write mode' and putted LB-value, which was taken from Scenarist's log, into 'settings>ISO write mode>options>layer break>user specified' field. I think, in such a way I'm guaranteed, that my disks will play in future on the my any new players. Because I heard from many people, that Scenarist is a "gold standart" of the authoring system.

I looked by VOBEdit to Scenarist's LB-nav' pack and saw, that it's SCR is unusual, it is unlike to non-LB nav' packs.

Also I saw, that Scenarist always adds in the it's image 32k gap before BUP, even through between IFO and BUP abounds with many VOBs. Although most probably this is it's caprice.

 

Now I test excellent burn software, especially it's 'Build mode', but I think, I must to select the same cell what I select in the Scenarist's 'Dual Layer editor'. I think this is a most reliable way to make fully compatible to spec disk.

 

Now I'm sure, that my Panasonic is very undemanding to spec.

 

Thanks a lot for such detailed explanations.

[Where is my Layer Break sector ?]

The only time to use "User Specified", IMO, is if you build the image already - eg in PgcEdit with mkisofs and you just wanna burn. In that case, I know PgcEdit passes the LB info on thru this setting. But do ensure it is turned back to "optimal" later.

What is a difference between images, created by PgcEdit and by Scenarist ?

Until now I burned many times Scenarist's image by old program. Scenarist's log contains LB LBA and I inserted this value into appropriate field. And I don't had any problems.

 

Also, looking back at my first post - it was kinda silly (this is not unusual biggrin.gif). Inserting 16 sectors of padding is useless, since the original LBA would be a multiple of 16.

As I understand, spec requires 32K padding in order to IFO and BUP files lay in the different ECC blocks.

 

P.S. I'm still very confused by situation and look any others method to verify, where is LB physically located on this burned disk. I'll be grateful for any help.

[Where is my Layer Break sector ?]

I learned a lesson well.

Up to now I've burned several +R DL exactly so, as you instruct me. I left 'user specified' value accidentally.

At first I wanted to burn Scenarist's image wiht LB LBA, calculated by Scenarist. Then I've changed my mind, but don't changed settings to 'automatic'.

 

I wanted to understand, is my Panasonic such undemanding, or I have faulty reasoning ?

I thought such wry LB is gross violation of spec, but .. it is a Panasonic :-)

 

Thanks a lot in any case! And especially thanks for you BEST burning software !

[Where is my Layer Break sector ?]

Thanks a lot for good explanation !

 

May be I've made an error during calculations and you will point to it.

This is IsoBuster's screenshot:

 

VOB with LB is selected on screenshot.

I know exactly, my stanalone don't play disks, burned by Nero in DVD-ROM preset.

 

What do you think, theoretically my player can to play fine DL with such wry LB ?

Moment of transition to 2-nd layer proved to absolutely invisible !

 

Thanks.

 

P.S. Sorry for my English. This is my not native language and I don't never speak it :-)

[Where is my Layer Break sector ?]

blutach

Thanks for quick reply.

 

According to the log, it breaks at 2,027,968

But, as I wrote, VOBEdit displays me, that LBA #2027968 contains nothing good.

Once I burned +R DL by ROMFormater. I've set LB incorrectly and my player have crashed on 2-nd layer.

 

Sounds like there's 16 sectors of padding.

Menu-domain in my scenario contains media-content and don't need to padding.

Moreover, IsoBuster displays me no padding.

Note - there is no need to specify an L0 landing zone for +R disks.

Sorry, I don't understood this.

I don't have mds-file when I burn Scenarist's image and I set LB manually for +R DL always. Is it wrong ?

Do I need to set "Calculate Optimal" in the Setting for +R DL always ?

 

 

LIGHTNING UK!

Thanks for reply!

So, is LB located in LBA #2027968 ?

If this true, I'm very confused by my standalone :-)

Since this LBA contains:

 

But LBA #2027952 contains:

[Where is my Layer Break sector ?]

Hi!

I've prepared DL-image by Scenarist and set the layer break at cell#13.

After compiling the image, Scenarist's discinfo.ifo had line: l a y e r 0 _ s i z e = 2 0 2 7 9 6 8.

I've set 2027968 to ImfBurn>Settings>Write>Options>Layer Break>User Specified field. Then I changed my mind. I've decided to test the seamless LB and I've selected "Build mode" in the ImgBurn. Before burning I've selected the same cell#13 from the list, suggested by ImfBurn, and "Seamless" from Options. In this box ImgBurn have told me, that Cell#13 will be locate at LBA #2027952.

2) I 23:27:52 Writing Layer 1... (LBA: 2027968 - 3773567)

 

What the hell?

Where is layer break, at 2027952 or 2027968 ?

Is manually set LB in "Setting" have effect to Build mode ?

 

Your old program displays info for this burned disk:

Layer Information:

Layer 0 Sectors: 2 027 968 (53,74%)

Layer 1 Sectors: 1 745 600 (46,26%)

 

But VOBEdit have displayed me, that cell's#13 first nav' pack located at 2027952 and LBA #2027968 contains nothing good.

Burned disk plays fine in my old enough Panasonic standalone.

 

Furthermore, I've created new image by your old program from this burned disk. Then I've selected ImgBurn>Tools>ISO>Display IFO Layer Break information and loaded newimage.mds. "Potential Layer Break Positions" box displays me LBA #2027952.

 

Where is my Layer Break sector ?

 

Thanks.
