Play files on external HD w/ NitoTV. HELP?

Right… Here is my setup.  I have a 1st gen Apple TV (40 gig model) which i have installed aTV Flash on (great product my the way).  I’ve got a 500 gig external hard drive attached to the USB port, and i have the Apple TV to use that for iTunes storage.

 

My question is:  Where do i put media files to open them w/ NitoTV?  And can NitoTV play DiVX files?

UPDATE: I’ve got it to play DiVX files without an issue, but, only if they are on the INTERNAL drive (in the Movies folder).  Any way to play  them off an external drive?
