CD disk image not recognized by Disk Utility

I downloaded an ISO disk image (and associated Cue sheet and CDT file) 
from http://www.mikedickson.org.uk/codetalkers/
but Tiger's Disk Utility 
does not recognize it and consequently is unable to burn it to an audio 
CD. It is an album that is not for sale and is only distributed as a 
free ISO image download. The ISO appears to be in some Windows specific 
format as the web page recommends IMGBURN to burn the CD.
Can anyone suggest a way to mount this image and burn the CD on a Mac? 
Are there utilities to convert one flavour of ISO into another for
example?
