[ale] NewbieQ: What image file format to burn a data DVD?

[Mills.J at ems-t.com (Mills, John M.)]

ALErs -

I would like to make a disk-image file and burn it to a DVD that I could
then mount on other Win and/or Lin systems' DVD-ROM drives. Content is a
Win32 file system of about 3 Gby.

Is ISO9660 format usable this way (using 'mkisofs'), or is there some
program analogous to 'mkisofs' that I should use to make such an image file?
Will typical Win32 DVD-burning software handle such an image file?

Any guidance to a beginner appreciated.

TIA.
