Shows how to backup DVD or CD iso or img image.
Mac OS X Disk Utility free
Toast Titanium 6 $80
Dragon Burn $43

Both Toast and Dragon Burn support external dvd burners natively.
However, for Disk Utility to burn to an external dvd burner you need to add your paticular dvd burner to your Mac OS X profile. Do this with patchburn (donationware). Now iDVD 5 and other apps can burn directly to your external burner. As far as I know there is no utility or program to change Book-Type (DVD R media to booktype DVD-ROM).



Here's some handy commandline commands

Browse to your DVD .iso image and open it.

If it's a CD .iso just choose a CD burner.

Since this is a DVD .iso I chose an external dvd burner. Eject disc after burning. Click Burn to begin burning.

Choose Select and browse to your .iso image. Choose DVD external burner (or superdrive if you have one) on the bottom.

Choose your Write Speed or better just leave it at Maximum Possible.

Choose After Writing: Eject and Close Disc. DAO (disc-at-once) and TAO (track-at-once) only apply to data and audio CDs. Press Record to begin burning.
