Tried to make a copy of my v.6.1 NAV DVD today with Drag-N-Drop CD+DVD . No luck. Very compressed files. has anyone ever made a successfull backup of the NAV software?

 

The problem for now, with making a backup seems to be the data on the v6.2 DvD ROM is 7.91G which won't fit on a standard blank dvd-r +/- disc. Next month dual layer dvd writers and discs will be released increasing the data capacity to over 8G. Then a backup of the disc should be possible as long as the NAV player will be able to read the dual layer disc.
