AppleTV+aTVFlash 4.1.5 and USB driver problem.

Hello …
I have ATV with installed aTVFlash ver. 4.1.5 … I have installed “Nito smart installer” in order to activate the USB connection but when I connect my USB drive nothing appear and if I select NitoTV-Movie I can see only the movies inside the Hdd of ATV … I have also create inside the USB Hdd the directory MyMedia/Movies but the problem is the same … nothing appear in NitoTV/Movie
Why I can’t find the USB drive?
Thank you.

Do you know the format of your USB drive?  The AppleTV will only support drives formatted in Mac OS and FAT32 formats.
