Since you have a DVD burner your in luck:
First visit
www.bootscriptor.org and download the latest version.
Then write a script (very similar to batch files). You can create a nice menu and capture keyboard key clicks from within your script. Help is available from the site.
Use the chain command to boot 2k and xp boot images or any other boot images that have .bin extensions. Use memdisk to boot 98 boot images or any other boot images that have .ima & .img extensions. (You can use WinImage to create .ima images -

Since your using a DVD you have plenty of room for many different os\'s and other software including ERD, Ghost, Drive Image, NTFS DOS, DOS, etc.
Also check out
www.nu2.nu and
www.tech-hints.com for more info regarding multi boot.
There are no limits to what we can accomplish!
Good Luck
