I don't see a way for my Harmony 550 to select a source
of input (e.g., TV, DVD Player, etc.). It can go to the
source screen and that's where it gets hung up. Without
the Harmony, just using my Samsung HDTV remote doing this
manually, I select the "Source" button on the Samsung
remote, then I use the Samsung remote's up-arrow or down-arrow
to navigate to a source I want, then I press the Samsung
remote's "Select" button to make the source screen go
away. The Harmony should be able to get to the Source
screen, but then what? It takes a human looking at the
screen to know how many up-arrow pushes or how many down-arrow
pushes are necessary to get to your desired source from
the source you are at at that moment. Because there are
no buttons on the Samsung remote dedicated to specific
sources, there is no single IR signal that can directly
select a particular source. The Samsung remote does not
select a source by name. Logically, I see no way for
the Harmony 550 remote to select the source input on a
Samsung TV.



Does anyone have any suggests or experience that would
help me around this?
