I've just had Sky Digital(Not +) installed. I have the Digibox(Grundig) connected to the TV via a scart cable and also via an ordinary RF cable. When I press the "E" button on my remote this normally brings up some channel info i.e. Channel Name, Time, and Audio Signal(Stereo or Mono)when the channel is not an AV connection ie. channels 1-99. Of course when I press the "E" button on the channel the scart is connected to the info is slightly different i.e. AV(1,2, or 3), Time and AV Sound(exactly that "AV Sound", no Mono or Stereo). I have had the tv automatically search for the Sky picture from the Digibox and set the channel to tv station number 20(UHF, E68, 847.25, Pal). Now here is the problem, when I press the "E" button while showing any of the Sky channel's the info shows the audio signal is "Mono". The audio broadcast on the AV channel would be appear to be in stereo but this is hard to verify. My question: is this normal or should the signal still be stereo although it is input using an RF cable. On my last decoder(not Sky) it did not matter whether I connected to the tv using a scart or RF I still get a stereo broadcast. Any clarification of this would be appreciated. PS: I have tried adjusting the settings on the Digibox i.e. Scart Control(on/off), RGB/PAL, 16.9/4.3 all to no avail. The audio setting on the digibox is always set to "Stereo".
