Hi All,

I recently decided to try to do a straight copy of my navigation DVD in case anything was to happen to the original disc. I tried multiple times but so far I've had bad luck.

The disc is over 4.7 GB so I'm using Memorex DVD+R DL discs. I was able to successfully burn a direct copy using Nero, but when I pop it in my car, I get an error saying to check the disc.

I've read up a bit and the only thing I can find thats even a clue, is that I have to change the book type to DVD-ROM when I burn, and the only way to do that is to use a special utility that may or may not work on my burner because its hardware specific.

Can anyone else shed some light on how to copy one of the newer dual layer navigation DVDs?

Which media did you use? It is pretty hard to find DL DVD media that the navi processor reads.

In any case, I would use the original disc in the car because a copy stresses the DVD drive and those are prone to fail even with original discs. A backup copy at home is OK in my opinion, if the original fails for some odd reason.

As above by diesel benz,, most home burn copies will not work due to poor reflectivity of the surface, and the error message comes up, check disc or no disc

My understanding is that the Nav disks are encrypted in some way so that people can't duplicate and sell. Understandable, but having one backup copy would be nice. I have never been able successfully to backup a Nav disk, even using special programs that copy byte by byte, so I have abandoned the effort. But I am not an expert, either. Good luck.

I am sure navteq would replace a faulty disk should the problem ever arise.

I believe the discs use Safedisc copy protection.

I wonder if a product like anydvd would help with that. It takes care of pretty much every kind of protection when backing up my dvd collection.

There's no encryption. Memorex sucks, that's your problem.
I use alcohol 120% or some similar program to make an ISO and then use a Verbatim disk (the ONLY decent DL disks out there). Hope that helps.

I've got a backup available..... PM me if interested.

You need to make a .ISO (image) of the original DVD then burn it on a DVD+R DL ..mine works.
Use MagicISO software from www.downloads.com or cnet

I had no problem with DVD+R DL media with Ashampoo Burning Studio. I think the key here is to make an ISO image and burn it. Don't just do a disc to disc copy. I've been running the backup for months. I was worried since we have so many potholes here in Wisconsin that the original would get all banged up.
