Yes, Microsoft CDROM extensions for DOS support both HSG and ISO-9660.  The 
differences between the specs are close to negligable.  

On the subject of Mac's and CDROM...  if you are using a vanilla HSG
or ISO-9660 disc that has lots of files and directories, expect to
wait a while when you pop in the disc.  The Mac has to parse the entire
file system before you can access a single file (not so with MSCDEX and DOS).
The only good thing about this is that you can use a disc with corrupt
path tables (because it doesn't USE them)... but then again, why would you?
