I ordered these from Monoprice.com (ph: 1-877-271-259) in California:
#5312 - 4X2 True Matrix HDMI® Switch w/ Remote (Rev. 3.0) $56.25
#3871 - 3ft 28AWG High Speed HDMI® Cable w/Ferrite Cores - Black $2.50
This switch allows me to take the two inputs (DVD player and Dish Antenna Receiver box) and switch the signals between the two televisions in the coach. Just like the DVD player, the Dish receiver can service just one television at a time.
