I've spent at least 2 hours glued to the computer screen looking for an answer to this. I know of HDMI transmitting devices that have a receiver and a transmitter, so you can stream video onto 2 devices at the same time. But what about any sort of device that allows multiple receivers so you can stream at least 3 devices at a time? The only things I've been able to find are the Nyrius Kit (http://nyrius.com/product/Wireless_HD_Video_Transmitter_Receiver.eng-44-specifications.html) and the Actiontec MyWirelessTV (http://www.actiontec.com/324.html). The Nyrius claims you can buy an additional receiver with it, but I don't know if the transmitter will simultaneously be sending the signal to both receivers at a time or if you can merely cycle through them. As for the Actiontec, multiple places have said you can also buy additional receivers for those and they work, but I haven't really seen their official website say that. There aren't any additional receivers I can see Actiontec currently selling (or any website for that matter) and the Nyrius device isn't available for another week, apparently. I need a device capable of doing this ASAP, any ideas? Would I be able to buy a pair of single-transmitting devices and use an HDMI splitter to connect to both of them so they can both connect to their respective receivers, or is that a bad idea?
