Had the same issue with my Miramar. You can split it out to your other TV's using the Quest box. I found a splitter at radio shack for a coax cable. I removed the sat in line from my DIRECTV unit, plugged that line into the in line on the splitter, then sent one line to my DIRECTV unit and the other line to the SAT in port on the Quest unit.
Select SAT on the quest box, and if I remember right, place your additional TV's on channel 3 or 4 and you can watch your DIRECTV in your bedroom or outside TV. Only took 5-10 min to install the splitter.
The above poster is right, it would be nice if they would have run HDMI line from the AV cubby out to the other TV's.
Hope this helps!!
