I advise extreme caution when considering wireless for video applications, particularly HDTV. It can often be problematic especially if there are other sources of interference and/or attenuation (barriers such as walls, cabinets, etc).

A reliable alternative worthy of consideration is MoCA. MoCA is a wired solution that utilizes coaxial cable wiring and can simultaneously operate with cable TV without creating an issue. I have been using a couple of NetGear MoCA bridges which easily transport Blu-ray video bitrates. The bridge will convert between the MoCA network and an Ethernet network.
