OK, I've just finished wiring my stuff together and...nothing shows up on my old tv to program the 950. I'm running a (yellow) composite cord from Output (#16 in the manual) to the (yellow) input of my tv. I'm also running cable into the 75 ohm pin input on the tv. As far as I can tell, there's no way to switch the tv to the composite input. Result? No on-screen display. Any ideas, gang? Shouldn't there be some sort of hard or software switch to a/v inputs? Is that the problem? (BTW, Channel 2-3 are cable channels. Is that relevant?)
