.dmg to cdr/dvd bootable

[Whiskey Jack]

Hello,

I made backups of my OS cds and put them in .dmg images. Now i need to burn them back to cd/dvd to see if I can. I would like to convert the .dmg file back into a bootable cd.

Cube 450 Mac OS X/9
External TDK 8x dvd burner

I also have Toast 6 Titanium. would this work better for this job then Disk copy?

Any input would be appreciated,

Thanks,

WJ
