Hi All, I have come for some advice off the masters as it seems you have already helped someone else with the same problem. I am new to this fourm so please forgive me if a get things wrong.

I have a legal copy of the Volvo RTI DVD Nav disks part no t1000-9524c and want to back it up to use instead of the originals. The manufactures of the disks is Navteq.

I have made a ISO copy using DVD Decrypter v3.5.4.0 using default settings. When I write the disk back using an LG DVD writer that supports booktype all I seem to dois turn the disk in to coasters (5 in total now )

When I write the Iso file back using DVD Decrypter v3.5.4.0 to a DL +R DL disk that I have set the booktype to “change for” dvd +r dl and the new setting to DVD –Rom.

A Ray say that there is no protection

The original disk size = 6.70GB or 7,201,683,456 bytes with no free bytes
The copied disk size = same as above and when viewed in windows it has the same file name and even says it’s a dvd –rom

When the copied disk is inserted the system does the following

1 message saying please wait, after about a minute you get another message
2 The disk in the dvd player cannot be read please check disk

Sorry for the long post just wanted to get as much info in as poss.

Any ideas would be greatly received Cheers for now
