Hmm.  I grabbed an ISO image I had handy:

$ file i386cd.iso 
i386cd.iso: ISO 9660 CD-ROM filesystem data 'NetBSD 1.6 i386              
 ' (bootable)

It seems to have the right block size (but I don't see how this is
controlled with mkisofs):

$ disklabel /dev/vnd0a 2>/dev/null |head 
# /dev/vnd0a:
type: vnd
disk: vnd
label: default label
flags:
bytes/sector: 512
sectors/track: 32
tracks/cylinder: 64
sectors/cylinder: 2048

And the root directory has stuff besides documentation:  

$ sudo mount -t cd9660 /dev/vnd0a /mnt
$ cd /mnt
$ ls -l; file *
total 5768
-r--r--r--  1 root  wheel     2048 Sep 19  2002 boot.catalog
-r--r--r--  1 root  wheel  2949120 Sep  8  2002 boot.i386
dr-xr-xr-x  4 root  wheel     2048 Sep 19  2002 i386
boot.catalog: data
boot.i386:    x86 boot sector
i386:         directory

I guess I'd suspect your burner program.  

I never booted a VAX from CD; I got mine going by netbooting them.  You
could do that, too, by booting your Windows box with a NetBSD Live CD.  It
would be much harder than booting from CD, of course, assuming you can
get/make one that boots.  

HTH.
