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 a lot !

Please, open your successfully written -R(DL) in the DVDDecrypter, select Mode->ISO->Read and post here info like this: Current Profile: DVD+R DL Disc Information: Status: Complete Erasable: No Sessions: 1 Sectors: 3 809 456 Size: 7 801 765 888 bytes Time: 846:34:56 (MM:SS:FF) Physical Format Information (ADIP): Disc ID: RITEK-D01-01 Book Type: DVD+R DL Part Version: 1 Disc Size: 120mm Maximum Read Rate: Not Specified Number of Layers: 2 Track Path: Opposite Track Path (OTP) Linear Density: 0.293 um/bit Track Density: 0.74 um/track First Physical Sector of Data Area: 196 608 Last Physical Sector of Data Area: 16 580 607 Last Physical Sector in Layer 0: 2 283 519 Physical Format Information (Last Recorded): Disc ID: RITEK-D01-01 Book Type: DVD-ROM Part Version: 1 Disc Size: 120mm Maximum Read Rate: Not Specified Number of Layers: 2 Track Path: Opposite Track Path (OTP) Linear Density: 0.293 um/bit Track Density: 0.74 um/track First Physical Sector of Data Area: 196 608 Last Physical Sector of Data Area: 16 224 079 Last Physical Sector in Layer 0: 2 279 599 Layer Information: Layer 0 Sectors: 2 082 992 (54,68%) Layer 1 Sectors: 1 726 464 (45,32%) Thanks !

TheShadowRunner 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 ?

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!

Oooh! (He is sighing of relief) Thanks a lot!

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.

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.

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.

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.

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. 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.

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 !

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 :-)
