tsk,tsk stop that you should not have to be told that!
you have failed to tell how you converted the file to iso, or I missed it why is it that that prog is not getting slandered on there support site.
I think your file is just to big or your media is crap or has just crapped out towards the outer rim if you don't wish to try the new media and quit being cheap,
you can try to compress this image in shrink or similar by pushing ctrl+I you will be able to select this iso and add you a custom output size to fit just inside of the first number in the log section that I quoted if this don't work I'll take up drinking hell if it does I'll take up drinking well either way let us know I've got drinking to catch up on!
