CDRWin can burn cue/bins and isos to...and I don't find it all that diffcult to use, but you are probably right, it's UI isn't the most intuitive in the world.
CDRWin is the only program I use...it can burn cue/bin, burn ISO, write audio CDs, extract CD sectors, you can even use it to build a .ISO file from a bunch of files on your hard drive and not burn it.
This came in handy once when I had downloaded a linux distro that didn't come in .ISO format, then I could make my own .ISO
Just curious can fireburner extract sectors? Every guide I've ever seen to making your own bootable Win2kSp2 CD uses CDRWin to extract the bootsector...
