Make CD from DVD

Barney Rubble · #1 01-21-2009, 07:49 AM

Let's say I am making a navigation CD from my existing navigation DVD because I want to test a CD based navigation unit.

I have successfully backed up my navigation DVD and confirmed that this backup works in a Mk4 navigation unit.

The CD unit I am wanting to test is a VDO Dayton.
I know that backup CDs have worked in this unit previously, but I don't have any of those earlier tested CDs to use this time.

Can someone please step-by-step me through the process of getting the DVD files onto the CD in readable format?

I have used DVD decrypter, Clone CD Clone DVD, Image Burn and UltraISO previously.

Thanks

No special steps.

Simply copy across.

Of course, you must reduce total size by deleting unwanted information such as POI data in other languages

Jochen, which software are you using? I just do a direct clone of the DVD onto CD?
If it's not too much to ask, could you step by step it for me?
Thanks.

My favourite to burn images is www.imgburn.com

There is no secret, you just need to remember that a DVD holds 2GB but a CD holds max 700MB. So you have to reduce the size of the DVD by deleting files you don't want. Eg: if your DVD is full, you have to delete 1.3GB of data to fit it on a CD.

Exactly what files to delete depends on your preferences.
The files that take up a lot of space are POIs, and the map disc is normally laid out in 6 languages

So if you only use one language, delete the other 5 you don't want.

Or alternatively, delete POI categories you don't want

Without seeing your particular map disc and without knowing what language POIs you want, I cannot say anything more specific.

But still.... even if delete ALL languages (POI), the map by itself takes approx 3,2 Gb (of course it we are talking about 2009-1 maps)..... How to reduce the map files? I do not see the way

Jochen, map disk is 400Mb on DVD so no problem with size.
I did use ImgBurn, and wrote the DVD image to the CD, but the Nav system didn't recognize that a CD was in it.

Map for Mk3 (CD) and map for mk4 (DVD) have a different data format...

True...!!
