I have rearranged a lot of pictures, trying to make a DVD cd to be played in my stand-alone-dvd-player.

Lets say; I added pictures of 1Gb total, and when I use the program it says that the totat disk space aquired is 455Mb (how is that possible)
As I understand - the program compresses the images, which I don't like..

Second, it should be possible to add 99 catalogues and 99 pictures = 9801 pictures. But I haven't used more than 800 pictures...
Why ?

Anyone had the same problems ?
