I have an OEM DVD for the 2008-1 High - (supplied by local dealer and therefore all legit and paid for) and have tried following the routine suggested for using Imgburn to make a DVD-R for what would effectively be a backup disc and got nowhere.

The instructions all seem to work - apart from the choice:

Set Menu Mode - ISO Write

which does not appear to be in Imgburn V2.4.0.0 - or at least I can't find it.

There is also a difference of about 100Kb between the OEM DVD and the ISO image, but all the filenames match. Burn speed is always set to 1x.

I have tried two different suppliers DVD-R (Verbatim and TDK) and both discs are rejected by the Mk4 Nav. The TDK disk is rejected much quicker than the Verbatim version.

Anyone got any ideas? Have Navteq put something there that Imgburn can't see or what? Am I doing it wrong? Have I got a drive that prefers the DVD+R variant?

I'm using V29 of the OS - which was also OEM and loaded by the dealer.
