Am I right in thinking that this will work? Xbox, WDTV, Sky HD, Blu-ray Player each connected by HDMI to Onkyo AV Receiver. Onkyo Receiver connected to a active HDMI splitter. HDMI splitter connected to main TV and a 8m HDMI cable (or HDMI over Cat5/6 cable in the future) to other room's TV. Then using a Harmony remote and IR sender, I could control everything connected to the Onkyo AV receiver in the other room? E.g. watch netflix on the Xbox, Sky and a Blu-ray in the other room. If this is correct, is there an IR sender that can handle all the different signals?
