Double checking grub-install -- revisited ??

Hi;

I have started this thread again as a new thread.  The previous "Double
checking grub-install ??" lead off in all kinds of plausible directions.
I think I now have more of a focus.

To recap:

I am getting a double Fedora grub splashimage at boot.  I have a dual
boot system with WindowsXP on sda and Fedora 9 on sdb.  I have some
experience with installing grub but made a typo type mistake during a
grub install a month ago and I think (??) that might have been the root
of my double splashimage problem.

To check the mbr, I ran on /dev/sda:
~]# dd bs=512 count=1 if=/dev/sda | od -Ax -tx1z -v 

it returned:
...

>........<.u.....<
...

[Notice the GRUB string on the second and third line and Error on the
fourth line]

Then, I ran on /dev/sdb:
]# dd bs=512 count=1 if=/dev/sdb | od -Ax -tx1z -v 

it returned:
...
000160 7c be 85 7d e8 40 00 eb 0e be 8a 7d e8 38 00 eb
>|..}. at .....}.8..<

[Notice the GRUB string on the second and third line as well, and Error
on the fourth line]

Could this double grub be the source of my problem ?
If it is, how do I remove it (from sdb -- I presume)?  

Others have suggested that the double splashimage is just a video mode
switch but then how do I account for the grub appearing on both mbr's
