How to best burn a 1:1 clone of a DVD using Parallel Layer Paths?

Recommended Posts

Just ran into one of these for the first time... a commercial DVD I am trying to back up using which has Parallel Layer Paths instead of the usual Opposite Layer Paths.

 

I figured it would be a simple operation, but I encountered error messages.

 

The DVD is Day of the Dead 2008 R1. Here's Anydvd 6.4.1.2, DVDInfo 4.79, and ImgBurn 2.4.1.0's info pages of the disc:

Creating an image doesn't seem to cause any problems. I forced the MDS creation setting to "Yes".

However, when I go to write the image, I get the following message:

I went ahead and clicked "Yes". I noticed that the first layer was changed from (LBA: 0 - 1841183) to (LBA: 0 -1855407) and the second layer was changed from (LBA: 1841184 - 3705696) to (LBA: 1855407 - 3705696).

 

Here's ImgBurn's log of the read and write process:

I'm wondering why ImgBurn was not able to preserve the original layer sizes of 1,841,184 and 1,864,513 (just written as opposite layer paths instead of parallel layer paths)?

 

In fact, just for kicks, I also tried doing a 1:1 copy with CloneCD and Nero 8's "DVD Copy" function. These were unable to set the book type to DVD-ROM for some reason (CloneCD doesn't do booktype directly, but I used Liteon's Booktype - Bitsetting Utility 1.3.5 to write to the EEPROM of my drive so that DVD-ROM always gets set, and it didn't work with CloneCD). However, both of these applications set DIFFERENT layer break positions.

 

Nero 8.3.2.1 looks like it did the layer break at exactly 50%:

CloneCD 5.3.1.0 did it at 56.32% (I think it may have burnt to the outside edge of the disc for the first layer):

Do any of you guys have any experience backing up a commercial DVD with parallel layers? Did I do this the best way I could, or, do you have any suggestions or tips on how to do this better?

Because L1 is bigger than L0 and that can't happen with OTP discs.

 

Follow this guide (use X:\VIDEO_TS as the source) and see which layerbreak options you get. Use the Preview button to find a layerbreak where a small pause will be less noticeable.

Oh, I see. I didn't even think of that... there wouldn't be enough room for the second layer!

 

I'm still wondering how ImgBurn deceided where to place the new layer break position. For example, with Nero it was exactly 50.00%, but with ImgBurn it was 50.07%.

 

Anyway, if the copy works fine, the layer break pause really doesn't bother me. But it's nice to know that I could manually set the layer break if I really wanted to, so thanks for the link!

I'm kind of curious as to why the DVD has to be remastered (ripped first) when creating a new layer break position.

 

In the case of this parallel track path DVD, three different applications inserted their own layer break positions... one of them (CloneCD) inserted one that was radically different than the other two (Nero and ImgBurn).

 

If the applications can set a new layer break position on a 1:1 ISO, why can't the user?
