HONDA/ALPINE DVD copy

[TrickyG]

I have problems making a backup copy of the newest DVD I got for my HONDA/ALPINE DVD based Nav system. With the original one I got with my car I had no problems. I made a copy with ImgBurn (ok, I took the image and burned the image to a blank DVD) and it worked, even with DVD-R DL. Below I am trying to explain my findings that I do not know what to do with

 

Now I got the new version I wanted to copy as well as the original, but I have problems as the DVD is not accepted by the Nav system. It is read but then reported as "incorrect disk". Looks like there's been a new method of copy protection implemented in the updated SW of the Nav system. The old system did not care about the differenc between the Parallel Track Path (PTP) vs. Opposite Track Path (OTP)diffrence, neither did it care about the fact the DVD-R DL did not break the layers at exactly the same point.

 

As I have not expected any problems, I don't have the ImgBurn logs from buirning my DVDs. And yes, I have tried with the DVD+R DL (Verbatim, the best on the market as I've been told). But I do have the disk information files that I am posting below.

 

The main differences I have observed are:

Disc Information section: size of the copy differs a little bit (much less than it did with the previous version). the copy is somewhat bigger.

TOC Information section: Track 01 and LeadOut values are as well slighly larger

Physical Format Information secion contains several differences (and this is valid for both Layers):

- the copy contains the "Disc ID" parameter, that is not present for the original

- the book type of the copy is of course not DVD-ROM - can this be changed for the copy?

- The Track Path is different PTP/OTP) and I have observed this in anopther topic to perhaps be the basic copy protection used - any way of getting around this?

- while the First Phyisical Sector of Data Area perfactly match, the Last Physical Sector of Data Area and the Last Physical Sector in Layer do not match. In fact, the original lists a very funny figure for the Last Physical Sector in Layer to be zero (0). Now, this might reveal I don't know much about the way these things work but how can the last one be at the very beginning

 

So, here are the Disk Information lists from ImgBurn as copy/pasted:

Did I get it right: the software writters that wanted to prevent the DVD copies from being usable can read the same parameters just like ImgBurn so they can easily detect the copy and block it from execution, right? But, are there any ways of getting the copy more similar to the original? I don't know why but feel that by having the disc return PTP instead of PTP the problem might be solved... Any ideas out there?

[LIGHTNING UK!]

You can't change the 'Track Path'. Writable discs are always going to be OTP.

 

The book type of the copy *is* DVD-ROM. Look at it in the 'Physical Format Information (Last Recorded)' block.

 

Writable discs always have a Disc ID. Pressed ones don't.

 

So to answer your question...

 

But, are there any ways of getting the copy more similar to the original?

 

Nope, sorry.
