AFP mount errors

Hello everyone.

I have nitoTV from ATV Flash 3.3.1 installed on my Apple TV 2.2. No other ATV Flash components are installed. I have no trouble connecting via AFP to my Mac. However, when I try to connect to my new Thecus N4100 Pro NAS (silent, fast, awesome box!), I get the following error:

mount_afp: the mount flags are 0000 the altflags are 0020
mount_afp: AFPMountURL returned error 22, errno is 2

I have no trouble connecting to the NAS from my Mac. Any thoughts on why the nitoTV can’t mount the volume? What do these errors mean?
