I would love to see these channels as well, but as my grandmother used to say, sh*t in one hand and want in the other, that is where I think we probably are on getting these with both providers.
I guess that you could get 4DTV if you really wanted American Life and get it in fixed key off of AMC 18 at 105 degrees west, of course you would have to have a C-Band dish. Also, RTN is available on many local digital sub channels, here in the Birmingham market it is on the NBC affiliate WVTM.
Also, you can get it off of AMC-9 at 83 degrees west in the clear with a FTA receiver.
