Here's a NEWB Question- I'm about to buy an XDS, but can't find anything on the forums about how it works with multiple TVs. If I set the XDS up in my living room, can I use it to watch media on my TV in the bedroom? Do I need a second receiver? I have Verizon Fios decoder boxes connected on each of these TVs. How does that affect the wiring/sending of signal? Thanks.
The box plugs into a TV like any other device. If you want to watch it on a second tv, you need to either: unplug it from the first and plug it into the second.... Or physically run wires to both TVs. Pretty much the same way you'd use 1 VCR with 2 TVs or 1 DVD player with 2 TVs.
As for the internet access. I'm not familiar with your setup. I don't know what a Verizon FIOS decoder box is. I have FIOS, but it comes into my house and connects to a router/modem. The router is wi-fi and I have 2 rokus connected to 2 tvs over wi-fi.
The Roku has 1 ethernet jack for internet and also wi-fi capabilities.
