Well after a frustrating number of weeks and Help provided here !
I have finally connected my tivo premiere to both hdmi main tv and also to a spliter to send signal to other rooms in the house.
I also use if remotes in many rooms to control the main comcast box as well as tivo unit.
these are radio shack models as well as other makes, they all work on the same frequency etc.
But the main point is that I ended up using a simple rf modulator picked up at a garage sale for 1.00
While at first I could not get this to work and ordered a different model which I never could get to work for some reason.
Two things that I think i learned. One you must come off the tivo unit with the composite video out use tivo
numbers 5 and 6 (Composite Video Output)
when i tried using numbers 4 composite video it would not work.
Numbers I refer to are Back panel reference numbers in tivo booklet on setup.
Putting the tv set on channel 3 and simply putting remote tv's on channel 3 works, However I will also admit
that I changed the cables, possibly the cables i was using were bad ?
Hope this helps someone else, as mentioned I was guided by this forum.
THANK YOU !
