Interesting diagram.... BUT...
I wired mine exactly as this one but the picture displayed on the TV is from the DVD when in record mode. Sometimes I want to record on the dvd from the in built tuner on analogue whilst watching the STB on digital but the STB allows pass through of the signal from the recorder via the scart and this overides the digital STB signal. I have 2 scarts on the DVD recorder TV and AUX 1 plus a set of phonos (3) 2 audio and 1 video AUX 2 plus the RF pass through system and 2 audio out phonos.
Basically I can record digital from the STB and watch analogue on the TV via the RF but not the other way round.
Help anyone......
