Sorry, wrong key! Sent to early. My receiver does not have s-video input/output so I am forced to use the following on my TV (RCA46):
INPUT 1, S-video(DVD), INPUT 2, RCA (DBS) Antenna A, Coaxial (local antenna) and Antenna B, Coaxial
(VCR). Access to Antenna B is via the TV menu, channel, and signal source. I then set up Macro 2 to select this. (Setup, 995, Macro2, TV, Menu, 5(channel),3 (signal source), 2, (ANT B), 0 (exit),
0(exit), 03 (channel), VCR, Setup) A similar sequence was set up on Macro1 to reverse this one.
I chose the macros because the sequence would'nt fit on the L keys which are set up like so:

View local antenna "1L"
SETUP, 995, 1L, RCVR, POWER, 7 (output), TV, POWER, 04, (chan), SETUP

View DBS "2L"
