Disc image of dual layer DVD

[davea300]

Hi

Last night I created a disc image of a dual layer dvd using my intel macbook with a superdrive. I used the Disc Utility program on OSX and my drive supports reading and writing of dual layer dvds.

When I put the dvd in the drive it showed 7.8GB of data on the disc. When I created the disc image the resulting file was only 4.7GB in size.

I didn't see any error messages when I created the image and it seemed to go through the process fine.

I haven't burned the image to disc yet but wanted to know if I have done anything wrong? I thought the image file would be the same size as the files on disc?

Apparently (I'm a Windows user) you can do it with the Disk Utility program if it doesn't support dual layers disks I quote from a post in another forum (it's buried so hence the copy > paste)

Go into your Disk Utility and create a 9GB IMG file. Put your 8GBs of files in the image file then mount it. DVD Player should now be able to play it as a DVD. If this is indeed the fact, you can use the utility "Burn" to burn the IMG file.

Failing that I've head good things about Toast it's not free, normal retail is $99.99 if you want to do this on a regular basis this may be the best way, dual layer fully supported.
