Hi

I have a genuine 2008-2 Navigation DVD disk (DL) from BMW.I would like to ask is it possible to download all data from DVD to the computer,add speed cameras (POI) and burn it again on DL DVD.

Previously I tried to copy original DVD (DL) to Verbatim (DL) with 2x,4x speed no luck, when I put it in DVD drive could't read it.

Are there any DVD protections?
Is it a speed issue.As well I tried to burn it on 1x,2x,4x,8x no luck.

Thanks
