ATV flash doesn't see my "My Book Elite 1.5tb"

I formatted my hard drive to mac os extended, and the ATV will not see the drive am I doing something wrong?

Has the Smart Installer been ran?

I did figure out I had to disable the WD smartware vcd start up. It sees it now but it will not play my dvds i ripped with iRip.

There’s a guide that outlines how DVD playback works here:
