In addition to moving the UHF antenna to the distant room (or some central location, 6' up a wall with a length of coax, ...), you might also try seeing how well the supplied remote works if you switch to the B range. If you display the System Info screen, TV2 should now say UHF Pro A range. Remove the battery cover and change switch from A to B and then push Record button. System Info should change to B range and that MIGHT be enough to control it from 3 stories away. You can get more distance with the B range, but you'd have to try to see if it was enough.
