What sorts of devices can this receive? I do not have cable tv (except through Sling) or any OTA channels at the location where my google-tv blu ray player is connected. I do have a WD TV live plus with HDMI output. I also have an ACER computer with HDMI output. Would it make sense to connect either of these to the NSZ-GT1? For example, if I connected my computer which can run the Windows Sling App, could I define the input as the Dish Network which feeds my SlingPlayer so that google-tv would then search on and know about this content natively?
