Need help burning DVD-ROM disk to DVD-R

[FENDERTWIN]

So I've got a Navigation DVD-ROM disk that is used in a car nav system. I need to make a copy of it, and I know it's 2 layers, so I throw it into DVD Decrypter, select FILE, and I get an error saying that it "UDF File Parsing System Failed" and "Cannot find VIDEO_TS folder"

Does anyone have any suggestions as to how I can burn a copy of this disk. Obviously I need to make it fit on a normal DVD-R disk, but with DVD Decrypter not working, I'm not sure how to do it. Thanks.

If it's a Data disc, you may be SOL.

You can't just "throw away" some of the data. And most of the discs used by those navigation systems aren't video, they're big ol' bunches of data.

DVD-ROM is not dvd-video so I'm moving this to the off topic->computer section.

Well, I think I'm screwed. I tried DVD Shrink and it can't recognize the DVD-ROM disk, so I can't even shrink it down to fit on a DVD-R. Any other suggestions?

Sorry about posting it in the incorrect section. Thanks for moving it.
