Your text is a bit confusing, but from what I've understand, you used a normal (700MB) cd and normal dvd's (4,5gb) to burn a ghost 2003 image.
First question, does norton ghost allow you to have hybrid writing (DVD/CD for the same image file)?
Secondly, are the cd's readable (you can access the contents) on your/others computer(s)?
Thirdly, which burner are you using? Has it ever crashed before?
