If the receiver gets internet it will work. Normal setup is from a router or modem to the mag, but advanced networking will work if setup correctly and there is enough bandwidth to cover streaming.
It will work anywhere there is internet running to it, doesn't check how it gets that internet connection. Make sure you also set the tv resolution to something both tvs can use too, to make sure you don't run into issues there.
i have people who stay in hotels and they plug em into their TVs . as the man above says make sure you have it selected to NTSC/PAL untill you know you can use 720p HDMI
