How do you cram 7.9 gb onto a standard DVD
I have a car with a nav system and a database on a DVD. I decided to back it up and put it in my computer only to discover that there were 7.9 gb on the DVD. I could read the DVD just fine so I copied it to a DVD9 double layer DVD, but the car cannot read it. I then looked at the original DVD using Nero and it is not a double layer DVD or double sided. So how does one get 7.9 gb onto a regular DVD and how can it be backed up? I have googled this problem and all hits say that you cannot get that much data on a DVD unless it is a double layer or double sided. The original is niether, It has a label on one side so it is not doulbe sided. What is going on? Anybody have a clue?

the original must be double layer if it has 7.9 GB, what about splitting the data on 2 dvd-r's?"One day men will look back and say I gave birth to the 20th Century". Jack The Ripper - 1888

Those data DVDs are written in a different way to a video DVD, AFAIK - I think they are written PTP instead of OTP. So there is no way to copy them unless they are a DVD5 to begin with.
@looie - splitting may not be much good for a satnav disk
