*** Update 3/4/2013 ***
I used Brasero on my Fedora 17 and that burned a copy of Clonezilla quite nicely. Hooray! Of course, my clone didn't work, but that's another story.

Troubles
First, for convenience sake, I burned the first F12 Live CD using my Macbook's Disk Utility. But when I plopped the CD into my desktop, the boot never finished and the DVD player kept humming for about 45 minutes. Something definitely wrong there. Testing on a second PC yielded the same result.
Researching Google, I found that other people had similar problems if the application they burned the CD with burned the CD at too fast a rate. This causes the laser in the DVDs to have difficulty reading the source data. Guess I'll have to reburn that bad boy. I tossed that CD out and thought I'd give Linux tools a try. I didn't know this next stage was going to turn into a two-hour extravaganza.
Burning an ISO in Linux is Easy, No?
Starting from scratch on my Fedora 12 box, I popped in a blank CD and good old Nautilus CD/DVD creator pops up:
I dragged and dropped the ISO onto the blank CD:
Selected "Burn contents"
And POOF..nautilus immediately craps out with a buffer error in dmesg:
[ 78.116252] Buffer I/O error on device sr0, logical block 0
OK, so I guess I won't use that. Next, I try Brasero:
Same result. OK. So let me try cdrecord, from the CDR toolset. Things seems to go well and then ba-BANG:
wodim: Cannot fixate disk
What the? Thinking the media was bad, I yanked it out and put a new CD in the drive. Same result. OK, this is getting tiresome. Time to Google:
http://www.google.com/search?sourceid=chrome&ie=UTF-8&q=wodim:+Cannot+fixate+disk
Surfing around does not yield much usable information; however, one post hinted at a drive or BIOS issue. I rebooted and checked the BIOS..nothing far from standard there. So I figured I'd run cdrecord again using the -dummy switch that means "do everything the burn will do, except turn off the laser." So I did this, again using another CD. If you're counting, that's three.
I first ran a scanbus:
[sodo@computer ~]$ cdrecord -scanbus
scsibus2: 2,0,0
200) 'HL-DT-ST' 'DVD+-RW GH50N ' 'B103' Removable CD-ROM 2,1,0

204) * 2,5,0
205) * 2,6,0
206) * 2,7,0

Then I ran cdrecord with the dummy parameter:
[sodo@computer ~]$ cdrecord -v -tao driveropts=burnfree -dummy -dev=2,0,0 Downloads/Fedora-14-i686-Live-Desktop.iso

OK! So this time, the "fake" burn worked! That's promising. I then ran the "real" burn (same command without the -dummy parameter) and prayed that it would work:

Ho HO! It worked!! Fabulous. But why?
It seems I made two changes that could have an effect:
1) I rebooted the computer
2) I used a different disc
My bet is on #2. But if you think differently, let me know. I'm just glad to having a working process for burning ISOs to a CD!
Cheers,
