Weird. I set the H20 output to 480i. Plug composite out to a VCR input- can see the video fine. Plug it into the SA Tivo (540 series) in 7.2 guided setup and the video is black. Cycled power on the SA Tivo, and same thing. Anyone see this before? This is a newly installed H20 (MFR code 600) capable of recieving mpeg4 local channels- the only reason I have an HD reciever. Variations- Same result if using SVideo Same result if power cycle both Same result on another 540 in another room. Any ideas anyone???
