If anyone can help with this, I would appreciate it.

 

I have burned a lot of discs over the years, and never had many issue; always use good burners and media (update firmware, Verbatim disc, etc.)

 

I am trying to make a working backup of my navigation dvd for my car. I learned long ago with kids that you need to make backups, as they love pressing buttons and handling discs.

 

Here is the info of the original disc ISO:

I made an ISO of this disc, and burned a copy to a Verbatime DVD+R DL disc, with booktype set to DVD-ROM, and write speed 1x.

The copy burns fine. But when I put it in the navigation drive, the disc is not recognized. "DVD not readable/wrong type"; some type of message like that.

 

I have made about 3 copies, all with the same results.

 

So here's where I am:

 

- I think the PTP vs. OTP has something to do with it, but I'm not sure.

- This disc info for the original disc and copy are not the same; shouldn't they be? I suspect it might be related to PTP vs. OTP, but again, not sure.

- Any ideas on how to deal with this? Do I need another app? (ex. PgcEdit)

 

Any pointers would be appreciated.
