Uploading directly to External HD

So I’ve been looking for a better way to upload rather than FTP (too slow for me) to my appleTV. I have tried to research setting a shared point AFP/SMB directly to the external HD connected to my apple TV but haven’t had any luck finding something. I know that AFP doesnt support the new firmware so that’s out.
Has anyone tried this?

FTP is the only way to transfer files to the AppleTV over the network. If you have a lot of media to transfer you can always connect the drive to your computer, load your media, and reconnect it to the AppleTV.

Try this, works like a charm:
