Here is what I used
An iogear wireless HDMI transmitter/switch. Between the tv and fireplace.
I now have HD in the living room, bedroom and outside. It has 2 HDMI inputs one HDMI output and a wireless receiver for the bedroom.
I can switch between the receiver and blue ray player. The transmitter is in the tv cabinet.
The nice thing about the iogear is it has a IR blaster so you can operate your devices in the living room from the bedroom.
I bought mine a B&H Camera online for 188.00 including shipping. I just plugged it in and it worked with no issues.
I thought about running cable to the bedroom till I got underneath the coach and realized it would have taken me all day and then some to install it.
