Hi, I would like to connect my Media Center PC to my TV/amp/loudspeakers, which are one floor below and on the other side of the house. I found this product, teh RCA WVS150 2.4Ghz A/V sender, which is supposed to perform this function quite nicely. My questions: 1) Has anyone used one of these? If so, what is the signal quality if traveling ~100 feet and through a couple walls? 2) It advertises that it also relays remote IR signal, but it's not clear whether this is just for RCA remotes or for any remote. 3) Will the 2.4GHz interfere with my WiFi router? Thanks!
