Since introducing a switchbox to my setup, I've lost the vcr presets and rescanning is only recognising ITV and Ch 4. Timer programming by Video plus numbers tapes the wrong channels and manual timer programming is impossible without the correct channels stored. My setup is: Sony TV - 1 SCART JVC VCR - 2 SCARTs DVD player - 1 SCART PACE digibox - 2 SCARTs Vivanco SBX95E Switchbox - 4 AV scart inputs - automatic/manual switching Configuration is: Aerial:- RF TV aerial to digibox RF from digibox to vcr RF IN RF from vcr RF OUT to TV SCART:- Digibox to vcr (AV1) Digibox to switchbox DVD to switchbox Switchbox to TV Viewing terrestrial and Sky is fine. Tuning this JVC VCR (model HR-A231EK) should be staightforward - there is an auto channel set function (frequency synthesized tuner) which should memorise all receivable channels in preset positions - but it's only picking up ITV and Ch 4. Any ideas ?
