Well, my old standby Nero failed to install, and IsoRecorder v2 wouldn't install, and v3 installs, but didn't appear to work.
I found however that the dvdburn.exe utility that is included with the Windows Server 2003 Resource Kit Tools did the trick.
I installed the resource kit tools under Vista, and then just had to open a cmd prompt and type:
dvdburn d: {imagefilename} /erase
where {imagefilename} was the fully qualified path to the iso image I wanted to burn.
I hope this helps someone!
