Spotmau PowerSuite 2009 has functions specifically (and only) to let you burn ISO files to CD!!!

I just bought the Spotmau PowerSuite 2009 version. Fairly to say it is really worth the money. It has lots of functions: some are great and some are just so. But the price is great. If you get all those functions elsewhere, you have to spend several hundred of dollars. Before I ordered Spotmau PowerSuite 2009 I had read an article about it from PC Magazine. I believe this is a rather fair review and I would like to recommend it to all:

One of the big challenges facing most operating system utilities is the simple fact that they're designed to run inside the OS. As a result, utilities makers have to design and program their software to take into account the resources-files and devices-that the OS needs to run. Utilities can't, therefore, always access resources to make changes to them. It's for this reason that some utilities, even built-in Microsoft Windows utilities (CHKDSK is one, if you choose to examine your boot disk) function only if you reboot your PC. Spotmau PowerSuite 2009 recognizes this issue and, as a result, runs directly from a bootable CD. As long as you have your PC configured to look for the CD first, all you have to do is put the disc into your CD/DVD drive and boot. The CD menu loads, and you can access the almost all of the various utilities without running Windows itself.

Spotmau PowerSuite 2009 is so centered around the CD, in fact, that it has no other means of working. When you order the suite from Spotmau, you choose either to receive a CD in the mail or to download an ISO image file. If you choose the latter, you also download a utility that functions specifically (and only) to let you burn ISO files to CD. You can also use your own CD creation software if you prefer, but be sure to specify that you want to work from an ISO image rather than create a standard data CD.

Booting from the CD calls up PowerSuite's main menu, a graphical DOS screen that divides the utilities into eight categories. Clicking on most of these categories also brings you to a graphical DOS screen. Older users might well experience twinges of nostalgia using Spotmau PowerSuite 2009: Those who entered PC computing in the Windows era might be a bit bemused by the bare-bones interface.
