Apple TV rocks, but I don't have the finances to purchase an Apple computer. So how did I get NitoTV fully installed on a 2.0.2 firmware released Apple TV with all the bells and whistles with only a Windows machine at my disposal?
The answer was essentially to do everything directly from the Apple TV.
If a version 1 OS.dmg is contained within the recovery image file (recovery.dmg) in the ~/Documents folder, NitoTV should be able to install/unlock all the useful bits and pieces like AFP support on the Apple TV.
The version 1 OS.dmg is available on the original Apple TVs with 1.0 firmware/backup partition. For subsequent released Apple TVs, the OS.dmg on the backup partition is a stripped down version missing key pieces.

$ md5 OS.dmg
MD5 (OS.dmg) = 30c4e468d235fb809acf9fb75c09b35f
Note the OS.dmg MD5 hash above matches the 2.0.2 firmware:-
1.0.0 (md5: 55b909196952ff72c93aaf3553cf661e)
1.1.0 (md5: e1cbe29ea136e0a34de09e0144bb5505)
2.0.2 (md5: 30c4e468d235fb809acf9fb75c09b35f)
2.1.0 (md5: 2783d7c2b27d8364bac3bde9de9d5287)
Thus, my Apple TV has a 2.0.2 firmware on the recovery partition. If I were to do a factory restore on my Apple TV, it would be thus running 2.0.2 software.
Recall, NitoTV requires a version 1.0 OS.dmg file to get AFP!

From version 0.6.4 onwards, Smart Installer will now grab the 10.4.9 Combo update and place it in the ~/Documents folder automatically
NitoTV can also setup AFP, so long as a version 1 OS.dmg is contained within the recovery image file in the ~/Documents folder.

As our recovery partition is 2.0.2 based, we need to create a customized recovery image with the OS.dmg based on a v1 Apple TV (rather than just a straight dd of the recovery partition).
$ sudo mount -uw /
$ sudo touch /.readwrite
the mount -uw and /.readwrite steps aren't necessary if you have already performed them in the past.
$ cd ~/Documents
get a copy of our 202 recovery partition as an image
$ sudo dd if=/dev/disk0s2 of=recovery_original.dmg bs=1m
here is some info on the image created
$ hdiutil imageinfo recovery_original.dmg

Note, the format is UDRW - meaning read/write - so we don't need to convert it to RW for editing
(otherwise, we would have had to do something like: hdiutil convert -format UDRW -o dest-rw.dmg source.dmg
- refer to http://dx4.org/linux/modifydmg.html regarding modifying read-only .dmg files.
)
Note, The OS.dmg contained within this image however is an image of format type: UDIF read-only compressed (zlib),
so if we wanted to mount it and modify the contents, we would need to convert to RW first!
Work from a clone of the image (don't modify the original); also note, NitoTV looks for a file named recovery.dmg

Obtain and upload the v1 OS.dmg file to the Apple TV :-
e.g. join the following two files together (fix the "xxx" first, then unzip)
