Thank you for using our forums about your question.
To answer your question, there is a link called SlingPlayer for WD TV® Media Players that list the requirements for the WD TV.
Hope this helps,

recently i purchased wdtv live and i was happy that the remote on it works like a charm.But unfortunately the application keeps disconnecting and changing channels is a big pain with a lag of almost ten sec.
what i can say is that the buffer size kept in the program is very low unlike the one on watch.slingbox.com.
slingbox + wdtv = deadly combination.
thanks slingbox team.
