222 I think does have coax output for tv1 and a home distribution port for tv2, so he can split off either of those. It has RCA out from receiver for tv2 he can connect to.
He can also split off of the line going to tv2 at any point between tv2 and the diplexer.
If he comes off the home distribution line going to TV 2, I believe he can go into modulator settings and turn tv1 on to home distribution port as well. Menu-6-1-5. So he could watch tv1 or tv2 off tv2's line.
Now if its a 222k without the ota module, then he has to use home distribution port and turn on the modulator for tv1
